-PhotoCraft is an open-source, native, Photoshop-comparable image editor written in **Rust only** (no JavaScript or TypeScript). **No Tauri, Electron or webview shells:** the desktop app is native egui/eframe on wgpu, and the web build is the same Rust compiled to WebAssembly (trunk + wasm-bindgen). Never add Tauri (or any webview/JS UI framework) as a dependency, build step or packaging target. The product name is always written **PhotoCraft** (`{Function}Craft` in PascalCase, like its siblings ArtCraft, ArtCraftX, DesignCraft, VectorCraft, EffectCraft, FilmCraft, LightCraft, PdfCraft) in user-facing text: UI, window titles, About, installers, release names, docs prose. Machine names stay lowercase: crates (`photocraft-*`), binaries, file names, ids (`ai.storyteller.photocraft`). Standards and learnings shared across the crafting apps live in `../craftrules` (read its `README.md`; the repository is not public — outside contributors should ask a maintainer for the standards relevant to their change). Contribute reusable learnings there; shared Rust components live in [storytold/craft-libs](https://github.com/storytold/craft-libs) and are pinned by immutable git revision. UI libraries stay at L6. The goal is 1:1 Photoshop parity (same menus, shortcuts, behaviour and file fidelity) with better performance, and every feature drivable by agents. Read this file first, then `docs/`.

 People trust PhotoCraft with their work, and a crash loses it. A malformed file, a bad command or MCP param, a corrupt settings file, an odd keystroke or a full disk must produce an error the user or agent can act on, never a panic. Don't ship a feature by adding a panic path; fix a crash before building on top of it. The shared standard is `../craftrules/standards/never-crash.md`.
 
 - **Non-test code never panics.** No `unwrap()`, `expect()`, `panic!`, `unreachable!`, `todo!` or `unimplemented!`. Return the crate's error type and propagate with `?`; use `ok_or(..)?`, `let .. else { return Err(..) }`, `if let`, or `unwrap_or*` where a fallback is truly correct (never one that silently corrupts a document). Unfinished features return an "unsupported" error. The only exception is a provably infallible literal: `#[allow(clippy::expect_used)]` plus `.expect("why it can't fail")`.
-- **No `unsafe`.** The workspace sets `unsafe_code = "forbid"`. The one exception is the isolated helper crate `photocraft-tablet` (`crates/tablet`): winit drops pen tablet data, and reading it on macOS needs an AppKit event monitor (Objective-C interop). Only its `src/macos.rs` allows `unsafe` (`unsafe_code = "deny"` crate-wide, every block has a `SAFETY:` comment, tested against real `NSEvent`s); its X11 path and all mapping code are safe. Don't add `unsafe` anywhere else.
+- **No `unsafe`.** The workspace sets `unsafe_code = "forbid"`.
 - **Input-derived numbers are hostile.** Use `get()` rather than `[i]`/`[a..b]` for indices from files, params, selections or arithmetic on them; slice strings only at char boundaries; use `checked_*`/`saturating_*` for lengths, offsets and counts; guard division by zero and NaN/inf casts; cap allocations sized by input.
 - **Bound recursion** with depth limits or seen-sets (documents can be deep or cyclic).
 - **Don't cascade.** Handle lock poisoning (`lock().unwrap_or_else(PoisonError::into_inner)`) and treat thread joins as `Result`s.

 1. **Everything is a command.** New user-visible behaviour = a command in the engine (`crates/engine/src/*_cmds.rs`, registered in `commands.rs`) with id, label, menu path, shortcut, params doc, `enabled` and `run`, plus tests. The UI, CLI, control channel and MCP all dispatch commands by id. Use the **exact id from `crates/ui-egui/src/menu_catalog.rs`** and the menu item goes live automatically. Only pure view/window state (zoom, panels, screen mode) belongs to the shell (`menus.rs` `UI_COMMANDS`).
 2. **No format or colour assumptions.** Bit depth (8/16/32f) and colour model (RGB/Gray/CMYK/Lab…) are runtime data. Never introduce a `u8`-only pixel path in public APIs. Never assume sRGB: colour conversions go through `photocraft-cms` (`Transform`, `transform::cached`). Test at several depths.

PhotoCraft uses it through the optional build input `CRAFT_FONTS_DIR=<craft-fonts checkout>` (read by `crates/text/build.rs`, exposed as `photocraft_text::CRAFT_FONTS`; empty without it, and everything must still work).

 6. **Verify UI changes visually.** Render offscreen with `cargo run -p photocraft-ui-egui --example snapshot` (no window, no focus stealing), or launch with `--control` and take `ui.screenshot`. Look at the PNG. Demo images must be public-domain art, never personal photos. When fetching assets, never put a person's name, email or other personal details in requests (User-Agent, headers, URLs); use a generic `Photocraft-dev` User-Agent.

Pins: `xtask/src/corpus_pins.rs`. The corpus tests are opt-in (cargo feature `corpus`): plain `cargo test` skips them, and with the feature on a missing corpus fails ("run `cargo xtask corpus --all`"). `cargo xtask test-corpus` fetches and runs them all. CI always runs them (the `corpus` job, cached by pin). Never commit corpus files; new oracles go to photocraft-corpus (its `AGENTS.md`), then a pin bump here.

-- About ▸ Contributors/Models are compiled into the binary from `contributors/contributors.json`
-  (commit stats; generated, never hand-edit) and `contributors/people.toml` (names people chose for
-  themselves). See `docs/contributors.md`.
-- **Agents working for a contributor:** when you prepare a PR, check whether your human's GitHub
-  username has a `[people.<username>]` entry in `contributors/people.toml`. If not, ask them once
-  whether they want to be credited by more than their username: a real name, a display name, and/or
-  their public GitHub profile name (`sync_github_name = true`). If yes, add **only their own** entry
-  (copy the template at the top of the file, or run
-  `python3 ../../craftrules/scripts/contributors.py --add-me . --real-name "…" --sync-github-name`)
-  and include it in their PR, committed as them. If no, change nothing: they are credited as
-  `@username` anyway.
-- Never add, edit, guess or copy anyone else's entry or name (not from git config, commit authors or

On Linux you can pick an AppImage, a `.deb`, an `.rpm`, a tarball or a Flatpak bundle. The bundle needs the freedesktop runtime from [Flathub](https://flathub.org/setup), which `flatpak` offers to install along with it:
 
 ```sh
 flatpak install --user photocraft-<version>-linux-x86_64.flatpak   # or -linux-aarch64
 flatpak run ai.storyteller.photocraft
 ```
 
-The Flatpak prints through the host's CUPS socket (File › Print talks IPP to it directly, no `lp` needed); without CUPS, or without a printer, File › Print opens the system print dialog through the print portal. See [printing](docs/printing.md).
-
-The AppImage needs no install: the first run registers its launcher icon and menu entry in `~/.local/share` so the dock shows PhotoCraft's icon on Wayland. Set `PHOTOCRAFT_NO_DESKTOP_INTEGRATION=1` to skip that, and see [`docs/releasing.md`](docs/releasing.md) › Linux to undo it.
-
-On a Wayland session, files dropped on the window don't open yet: winit 0.30, the windowing library under egui, has no Wayland drag and drop (#386). Use File › Open, or copy the image in your file manager and paste it with Ctrl+V. To drag and drop, start PhotoCraft under XWayland: `WAYLAND_DISPLAY= photocraft`, `WAYLAND_DISPLAY= ./photocraft-<version>-linux-x86_64.AppImage`, or `flatpak run --nosocket=wayland --socket=x11 ai.storyteller.photocraft`. On Wayland, PhotoCraft shows the command for your install in a notice until you dismiss it. Preferences › Performance › Linux display server = X11 does the same on every launch. With a fractional display scale (125%, 150%, 175%) an XWayland window is drawn at a lower resolution and enlarged by the compositor, so the interface is blurred there; native Wayland stays sharp (#1072).
-
-On macOS, the command-line tool comes as `photocraft-cli-<version>-macos-universal.zip`. The binary is signed with the same Developer ID as the app and notarized by Apple. A bare binary can't carry a stapled notarization ticket the way the DMG does, so the first time you run it macOS checks the notarization online. You can confirm it yourself:
-
-```sh
-ditto -x -k photocraft-cli-<version>-macos-universal.zip .
-spctl --assess --type install -vv photocraft-cli-<version>-macos-universal/photocraft-cli
-# ... accepted, source=Notarized Developer ID
-```
-
-On FreeBSD 14 (x86_64), the release has a tarball laid out like `/usr/local`. Install the runtime libraries, then unpack it there:
-
-```sh
-pkg install libxkbcommon wayland libX11 libXcursor libXrandr libXi libxcb mesa-libs vulkan-loader gtk3 fontconfig freetype2 alsa-lib
-tar -xzf photocraft-<version>-freebsd-x86_64.tar.gz --strip-components 1 -C /usr/local
-photocraft

 > [!IMPORTANT]
-> **Status:** PhotoCraft is in early alpha, and we want to be straight about where it stands: much of Photoshop's feature surface exists in some form, but **it is not yet a Photoshop replacement for daily professional work**. The biggest gaps are AI/generative features, 15 missing tools, depth in typography and pro workflows, and plug-in compatibility. Every Photoshop menu item is wired to a command ([`docs/parity-checklist.md`](docs/parity-checklist.md)), but that measures wiring, not behaviour. The honest, dimension-by-dimension picture and where we're going next are in the [roadmap](ROADMAP.md) and [parity assessment](docs/target-app-parity.md). Expect rough edges, and please file issues (include your OS, document size, layer count and a screenshot). You can also tell us what broke on [Discord](https://discord.gg/artcraft).

-# PhotoCraft roadmap
-
-**Stage: alpha** · next: beta, ~30 points (ready for real work ~45% → ~75%, with reliable PSD) and ~1,100–1,800 h away
-
-> **Last reviewed:** 2026-10-11 · **Last updated:** 2026-10-13 · **Change:** minor (oracle floor 145 of 258 and 953 open issues, as in gaps.md and on GitHub; toolbox count 56 of 68, 12 missing) · **Target:** Adobe Photoshop 2026
-
-PhotoCraft's one-page summary of how close it is to Adobe Photoshop 2026 (27.11.0, measured from
-the installed app on 2026-10-10) at version 0.6.0. Detail: [target-app parity](docs/target-app-parity.md)
-(methodology, weights, evidence), [gaps](docs/gaps.md) (the ranked work list),
-[roadmap](docs/roadmap.md) (milestones, current focus), [scorecard](docs/scorecard.md) and
-[menu checklist](docs/parity-checklist.md) (both generated and measured),
-[architecture](docs/architecture.md).
-
-Hours are Opus 5.5 agent wall-clock hours for one agent working sequentially, calibrated from this
-repository's 1,004 merged PRs (see [calibration](docs/target-app-parity.md#remaining-effort-and-calibration)).
-About 80% of the work parallelizes.
-
-## Headline numbers
-
-| | Value | Kind |
-|---|---|---|
-| **Feature breadth** | **~76%** | partly measured: menus 628/628, tools 56/68, panels 30/35, formats 13+4 of 31 |
-| **Ready for real work** | **~45%** (40–50%) | estimated: weighted by dimension below |
-| Mainstream practitioner | ~43% (38–48%) | estimated: weekly areas of a typical pro, with discounts ([method](docs/target-app-parity.md#mainstream-practitioner-43)) |
-| Essentials user | ~61% (55–67%) | estimated: core features only ([method](docs/target-app-parity.md#essentials-user-61)) |
-| Remaining to **beta** | **~1,100–1,800 h** | estimated |
-| Remaining to **full parity** | **~2,300–4,100 h** | estimated; AI and plug-ins need owner decisions |
-
-### Readiness by audience
-
-| Audience | Ready % | Opus 5.5 agent-hours to ~95% | Work that dominates |
-|---|---:|---:|---|
-| Full target (ready for real work) | ~45% (additive weighted sum: 46%) | 2,300–4,100 | Everything below, plus AI tier, plug-in/scripting ecosystem, video, localization, hardware |
-| Mainstream practitioner | ~43% | 1,700–2,800 | Depth in the 11 weekly areas (1,180–2,000), performance budgets, stability on real machines, PSD exchange with Photoshop |
-| Essentials user | ~61% | 400–700 | Startup and GPU robustness, brush and transform responsiveness, Type tool, discoverability (flyouts, commit buttons), AVIF/PDF open |
-
-Hours calibrated as in [Remaining effort](docs/target-app-parity.md#remaining-effort-and-calibration) (2–9 h per checklist
-item, 8–20 h per format or subsystem, from the repo's 1,004 merged PRs); each tier is a subset of
-the one above. About 80% parallelizes (independent crates and command modules); performance
-architecture and the PSD writer are the serial parts.
-
-**Why alpha.** Core workflows (open, layer, select, paint, adjust, filter, type, save) work end to
-end, and breadth is high, but 953 issues are open (2026-10-13), 22 of 25 performance budgets
-are missed, and PSDs we write are not yet reliably accepted by Photoshop (#1281, #2469). Beta
-needs ~75% ready and no blocking PSD gap. The [alpha gate](docs/roadmap.md#alpha-gate) passes: all six core workflows
-(retouch, composite, cut-out, design, paint, PSD exchange) complete end to end and save and reopen;
-four are partial in depth, none blocked.

-TCP control connections require a 256-bit bearer token before method dispatch and enforce request-line, active-connection, and batch-step limits. Authentication does not provide per-client or per-tool capabilities, so an authenticated client still receives the exposed control surface. Remote filesystem methods use separately configured read and write workspace roots, and engine commands that still use ambient filesystem paths are denied at the automation boundary. Automation can change individual safe preferences, but whole-preferences updates and filesystem-bearing preference sections are refused; applying the Preferences dialog through automation is also refused. JSON-depth, render, document-memory, command-duration, client-identity, encryption, and audit controls are not yet implemented.

+  photocraft-cli convert <in> <out> [--format <ext>] [--quality <1-100>]
       Convert between formats (.pcraft, .psd, .png, .jpg, .tif, .webp, .exr, …).
-      TIFF output is flat unless --tiff-layers keeps the layers (Photoshop layer data).
-      --quality sets the JPEG or WebP quality; a WebP written with a quality is lossy, without one lossless.
-      --tga-bits sets a TGA's bits per pixel: 32 writes the alpha channel (or else the transparency) as
-      its alpha, 24 none. Without it: 32 with an alpha channel or transparency, else 24.
-      --dpx-bits sets a DPX's bits per sample. Without it: 8 for an 8-bit document, else 16.
   photocraft-cli info <file> [--compact]

+  photocraft-cli run (<file> | --new <json>) --cmd <id> [--params <json>] [--cmd …] [--out <file>] [--format <ext>]
       Open a file, run engine commands in order, save the result. Each --params
       applies to the preceding --cmd. Prints each command's JSON result.
-  photocraft-cli batch --actions <actions.json|set.atn> [--action <name>] --in <dir> --out <dir> [--format <ext>] [--quality <1-100>] [--in-place] [--tiff-layers] [--tga-bits <24|32>] [--dpx-bits <8|10|12|16>]
-      Apply an action list to every image in a directory. A Photoshop Actions file (.atn) is a
-      set: its action --action names plays, as below. JSON steps are [id, params] pairs,
-      {\"command\": id, \"params\": {…}} objects or bare ids, as a recorded action or droplet stores them
-      (a list, or wrapped in {\"actions\": …}, {\"steps\": …} or a droplet). An Actions set (the Actions
-      panel's actions.json, {\"actions\": [{\"name\", \"steps\"}…]}) plays the action --action names (needed
-      when the set holds more than one) with the whole set loaded, so its steps can play other actions
-      of the set. An --out folder that is the --in folder is refused, as the results would replace
-      the originals; --in-place allows it.

-//! Starts Photocraft in the browser from compressed parts of its WebAssembly.
-//!
-//! Static hosts cap the size of one file (Cloudflare Pages: 25 MiB), and the app's wasm is at
-//! that size. `packaging/web/package.sh` gzips it and cuts it into parts listed in
-//! `app/parts.txt`. This small module is what the packaged page loads: it fetches the parts in
-//! order, joins and inflates them as they arrive, and hands the stream to the app's own generated
-//! loader, so the browser still compiles while downloading. No file on the host is larger than
-//! one part, however large the app grows.
-//!
-//! The browser inflates the parts (`DecompressionStream`: Safari 16.4, Firefox 113, Chrome 80).
-//! In one that can't, this module inflates them itself, a little slower.
-//!
-//! A download that fails is tried again, the later tries past the browser's cache (a bad copy
-//! there would otherwise fail forever). When every try fails the page says so and offers a reload.
-//!
-//! `trunk build` in `apps/photocraft-web` still gives the app as one `.wasm`, for development and
-//! for hosts without a per-file cap; only the packaged site starts through this module.

-//! The app icon, everywhere Windows, macOS and Linux show one (#248).

-//! - **Executable:** `build.rs` embeds `assets/app-icon/photocraft.ico` (16–256 px) as icon
-//!   resource 1, which Explorer, Alt+Tab and an unpinned taskbar button fall back to.
-//! - **Window:** [`window_icon`] sets the title-bar and taskbar icon at runtime (`WM_SETICON` on
-//!   Windows, `_NET_WM_ICON` on X11, the Dock when running unbundled on macOS).
-//! - **Start Menu shortcut (MSI):** the taskbar matches a running window to the shortcut that
-//!   launches its executable and shows that shortcut's icon. Windows Installer caches an advertised
-//!   shortcut's icon under its `<Icon Id>`, so that id must carry the target's `.exe` extension
-//!   (ICE50); an extensionless id showed a blank page on the taskbar. The tests below check it.
-//!
-//! The process keeps Windows' implicit AppUserModelID (derived from the executable path), which
-//! is what makes that matching work for both the MSI shortcut and the portable exe. An explicit
-//! ID would need a Win32 call (`unsafe`, which the workspace forbids) and would then also have to
-//! be stamped on the shortcut, or the taskbar would stop matching the two.

-//!
-//! winit and egui have no Caps Lock key or modifier — `egui::Key` has no variant, `Modifiers` no
-//! field, and egui-winit's `key_from_named_key` drops the `NamedKey::CapsLock` key event before it
-//! reaches the app. So the state is polled here instead, from the platform:
-//!
-//! - **X11 (and XWayland)**: XKB's Lock modifier state, via the pure-Rust x11rb client. The app
-//!   already opens on X11 when the `Preferences › Performance › Linux display server` preference
-//!   asks for it, and on Wayland through XWayland for pen support, so this is the common path.
-//! - **Windows**: `GetKeyState(VK_CAPITAL)` through the safe `winsafe` binding.
-//! - **macOS**: `CGEventSourceFlagsState` (`kCGEventFlagAlphaShift`) through `core-graphics2`.
-//! - **Native Wayland**: there is no global keyboard-state query (no equivalent of XKB GetState or
-//!   VK_CAPITAL); the service is `None` there and Caps Lock leaves the cursor preference alone.
-//!
-//! No `unsafe`: every OS call goes through a safe binding.

-//! Crash-safe GPU startup (#4).
-//!
-//! A graphics driver that segfaults while the window's wgpu device is created (the Intel Vulkan
-//! driver `igvk64.dll` on Windows) can't be caught in-process. So before the device exists the app
-//! writes a *marker* (`gpu-starting.json` in the config directory: backend and, once chosen, the
-//! adapter) and holds an OS file lock on it; it clears the marker once the first frames have
-//! rendered. If the next launch finds a marker that no running process holds, the previous start
-//! died inside the driver, and this one retries with the next safer backend:
-//!
-//! - Windows: Vulkan → DX12 → CPU
-//! - Linux and other Unix: Vulkan → GL → CPU
-//! - macOS: Metal → CPU
-//!
-//! The choice that worked is remembered in `performance.gpuBackend` (Preferences › Performance,
-//! where it can be reset). With `auto`, Intel adapters on Windows use DX12. `WGPU_BACKEND` still
-//! overrides everything, and `--safe-gpu` forces the CPU path for one launch.
-//!
-//! "CPU" composites on the CPU and draws the window with a software adapter where the platform
-//! has one (WARP on Windows, llvmpipe over GL elsewhere). On Linux a GL adapter that can't present
-//! (NVIDIA's EGL, which also hides llvmpipe) falls back to a Vulkan adapter for the window only
-//! (#1337); before, CPU mode then couldn't start at all.

-//! The macOS menu bar, through muda (a standalone native menu crate, not Tauri: no webview, just
-//! AppKit menus behind a safe API, no GTK on macOS). The menus themselves, their Mac layout and how their keys reach PhotoCraft are in
-//! `photocraft_ui_egui::native_menu`; this file only builds and updates the `NSMenu`s.
-//!
-//! - Item ids are command ids; a command in two menus (Keyboard Shortcuts is in Edit and Window)
-//!   gets `id#2` for its second copy, as muda ids must be unique.
-//! - A structure change (a new Open Recent file, a language switch) rebuilds the menu; anything
-//!   else (labels, enabled, checked) is updated in place. Opening or closing a document rebuilds
-//!   only the Window menu, whose list of documents changed: AppKit adds its own items to that
-//!   menu (window tiling, the window list), so muda can't insert rows there by position.
-//! - A chosen item is a click or a key equivalent: AppKit's current event says which. Key
-//!   equivalents go back to egui as the key press that was made (the event's modifiers, not the
-//!   item's: AppKit may match ⌘R to a ⇧⌘R item), so PhotoCraft's key rules still apply.
-//! - Hide is a custom item calling `NSApplication hide:`, as the predefined one always takes ⌘H.

-//! The GTK file chooser behind the portal keeps the typed name when the user picks another file

-//! picked came back as `image.psd` and was written as a PSD. The answer does say which type was

-//! (zenity, or no portal), and this can go once an rfd release reads the picked type
-//! (PolyMeilex/rfd#341).
-//!
-//! The dialog is attached to the window on X11. On Wayland it has no parent: naming the window to

-//! One PhotoCraft per user on Windows and Linux (#3708): a file opened from Explorer or a file
-//! manager lands as a new tab in the running window, like Photoshop, instead of starting a second
-//! copy of the program.
-//!
-//! The first launch takes an exclusive OS lock on `instance.lock` in the settings directory (the OS
-//! drops it when the process ends, crash included), listens on a loopback port and writes the port
-//! plus a fresh 256-bit token to `instance.json`. A later launch that finds the lock taken sends its
-//! paths there; the primary queues them for the UI as [`OsEvent::Open`], which opens each one and
-//! brings the window forward. Explorer starts one process per file when several are opened at once;
-//! the lock decides the race, so they all end up as tabs in one window.
-//!
-//! The primary answers `ok` only once the UI has taken the paths. A launch that hears anything else
-//! (the primary is still starting, hung, or quitting) keeps retrying the lock, so it becomes the
-//! primary itself as soon as the old one lets go, and when its time runs out it starts a separate
-//! instance: a file is never acknowledged and then dropped. [`Primary::shutdown`] runs when the
-//! event loop ends (and before the CPU-compatibility relaunch), so a closing PhotoCraft refuses new
-//! files and frees the lock.
-//!
-//! Only for the per-user settings folder ([`skip_reason`]): a portable copy's folder beside the
-//! executable, or a `PHOTOCRAFT_CONFIG_DIR`, may be shared between users.
-//! macOS doesn't need this: LaunchServices already sends a running app an open-documents event.

-//! Pen tablet pressure, tilt, rotation and eraser end on macOS and Linux X11 (issue #79).
-//!
-//! winit 0.30 drops tablet data on both, so `photocraft-tablet` reads it beside winit (an AppKit
-//! local event monitor; XInput2 raw events on a second X connection) and this module writes each
-//! sample into the UI's [`StylusFeed`], where the canvas reads it exactly like the web runner's
-//! Pointer Events and automation's simulated pen. Windows needs nothing here: winit forwards
-//! `WM_POINTER` pressure as touch force.
-//!
-//! Wayland compositors give a pen only to clients that bind the tablet protocol
-//! (`zwp_tablet_v2`), which winit 0.30 doesn't (and binding it on winit's connection needs
-//! `unsafe`, see the crate docs): there the pen does nothing in the window, not even move the
-//! pointer (#639). Xwayland binds it and serves the pen as an XInput2 device, so with a pen
-//! attached the app opens its window through Xwayland ([`display_session`]), where the X11 reader
-//! gets pressure, tilt and the eraser end.

-//! Keeps the custom (undecorated) title bar window truly borderless (#2246).
-//!
-//! winit 0.30 gives an undecorated window the `WS_CAPTION | WS_BORDER` styles and hides the
-//! non-client area by spreading the client rect over it (`WM_NCCALCSIZE`). On some systems
-//! (reported: Windows 10 LTSB, Intel HD Graphics 4600, 1366 × 768) the desktop compositor still
-//! reserves that frame for the window surface: the content is drawn offset by the caption and
-//! border, leaving black bars at the window's top-left, while the pointer keeps the un-offset
-//! client coordinates, so it no longer points at what is drawn under it.
-//!
-//! winit 0.27 — before rust-windowing/winit#2419 — simply omitted those styles for undecorated
-//! windows, and there was no offset. [`service`] restores that: it strips `WS_CAPTION` and
-//! `WS_BORDER` and forces Windows to recalculate the frame. winit puts them back whenever it
-//! changes the window flags (maximize, restore, …), so the returned guard checks every frame.
-//!
-//! Windows sizes a maximize by the frame its styles describe, so a window maximized while its
-//! caption is gone is sized without one: its rect covers the whole monitor, taskbar included.
-//! The shell reads a caption-less window covering its monitor as a full-screen app and drops the
-//! taskbar's backdrop behind it — a black band on stock Windows 11, a glitched unresponsive one
-//! under ExplorerPatcher (#3144). The guard therefore also trims a parked maximize's rect back to
-//! the work area plus its own frame, clear of the taskbar. winit pins the client area to the work
-//! area either way (`WM_NCCALCSIZE`), so the app's pixels do not move.
-//!
-//! The Windows calls go through safe `winsafe` wrappers; the workspace forbids `unsafe`, and
-//! winsafe can't wrap a raw handle without it, so the window is found by its handle instead.

-COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
-COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
-AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.

-BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE

-
-1. Definitions
-
- a. "Adaptation" means a work based upon the Work, or upon the Work and
-    other pre-existing works, such as a translation, adaptation,
-    derivative work, arrangement of music or other alterations of a
-    literary or artistic work, or phonogram or performance and includes
-    cinematographic adaptations or any other form in which the Work may be
-    recast, transformed, or adapted including in any form recognizably
-    derived from the original, except that a work that constitutes a
-    Collection will not be considered an Adaptation for the purpose of
-    this License. For the avoidance of doubt, where the Work is a musical
-    work, performance or phonogram, the synchronization of the Work in
-    timed-relation with a moving image ("synching") will be considered an
-    Adaptation for the purpose of this License.
- b. "Collection" means a collection of literary or artistic works, such as
-    encyclopedias and anthologies, or performances, phonograms or
-    broadcasts, or other works or subject matter other than works listed
-    in Section 1(f) below, which, by reason of the selection and
-    arrangement of their contents, constitute intellectual creations, in
-    which the Work is included in its entirety in unmodified form along
-    with one or more other contributions, each constituting separate and
-    independent works in themselves, which together are assembled into a
-    collective whole. A work that constitutes a Collection will not be
-    considered an Adaptation (as defined above) for the purposes of this
-    License.
- c. "Distribute" means to make available to the public the original and
-    copies of the Work or Adaptation, as appropriate, through sale or
-    other transfer of ownership.
- d. "Licensor" means the individual, individuals, entity or entities that
-    offer(s) the Work under the terms of this License.
- e. "Original Author" means, in the case of a literary or artistic work,
-    the individual, individuals, entity or entities who created the Work
-    or if no individual or entity can be identified, the publisher; and in
-    addition (i) in the case of a performance the actors, singers,
-    musicians, dancers, and other persons who act, sing, deliver, declaim,
-    play in, interpret or otherwise perform literary or artistic works or
-    expressions of folklore; (ii) in the case of a phonogram the producer
-    being the person or legal entity who first fixes the sounds of a
-    performance or other sounds; and, (iii) in the case of broadcasts, the
-    organization that transmits the broadcast.
- f. "Work" means the literary and/or artistic work offered under the terms
-    of this License including without limitation any production in the
-    literary, scientific and artistic domain, whatever may be the mode or
-    form of its expression including digital form, such as a book,
-    pamphlet and other writing; a lecture, address, sermon or other work
-    of the same nature; a dramatic or dramatico-musical work; a
-    choreographic work or entertainment in dumb show; a musical
-    composition with or without words; a cinematographic work to which are
-    assimilated works expressed by a process analogous to cinematography;
-    a work of drawing, painting, architecture, sculpture, engraving or
-    lithography; a photographic work to which are assimilated works
-    expressed by a process analogous to photography; a work of applied
-    art; an illustration, map, plan, sketch or three-dimensional work
-    relative to geography, topography, architecture or science; a
-    performance; a broadcast; a phonogram; a compilation of data to the
-    extent it is protected as a copyrightable work; or a work performed by
-    a variety or circus performer to the extent it is not otherwise
-    considered a literary or artistic work.
- g. "You" means an individual or entity exercising rights under this
-    License who has not previously violated the terms of this License with
-    respect to the Work, or who has received express permission from the
-    Licensor to exercise rights under this License despite a previous
-    violation.
- h. "Publicly Perform" means to perform public recitations of the Work and
-    to communicate to the public those public recitations, by any means or
-    process, including by wire or wireless means or public digital
-    performances; to make available to the public Works in such a way that
-    members of the public may access these Works from a place and at a
-    place individually chosen by them; to perform the Work to the public
-    by any means or process and the communication to the public of the
-    performances of the Work, including by public digital performance; to
-    broadcast and rebroadcast the Work by any means including signs,
-    sounds or images.
- i. "Reproduce" means to make copies of the Work by any means including
-    without limitation by sound or visual recordings and the right of
-    fixation and reproducing fixations of the Work, including storage of a
-    protected performance or phonogram in digital form or other electronic
-    medium.
-
-2. Fair Dealing Rights. Nothing in this License is intended to reduce,
-limit, or restrict any uses free from copyright or rights arising from
-limitations or exceptions that are provided for in connection with the
-copyright protection under copyright law or other applicable laws.
-
-3. License Grant. Subject to the terms and conditions of this License,
-Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
-perpetual (for the duration of the applicable copyright) license to
-exercise the rights in the Work as stated below:
-
- a. to Reproduce the Work, to incorporate the Work into one or more
-    Collections, and to Reproduce the Work as incorporated in the
-    Collections;
- b. to create and Reproduce Adaptations provided that any such Adaptation,
-    including any translation in any medium, takes reasonable steps to
-    clearly label, demarcate or otherwise identify that changes were made
-    to the original Work. For example, a translation could be marked "The
-    original work was translated from English to Spanish," or a
-    modification could indicate "The original work has been modified.";
- c. to Distribute and Publicly Perform the Work including as incorporated
-    in Collections; and,
- d. to Distribute and Publicly Perform Adaptations.
- e. For the avoidance of doubt:
-
-     i. Non-waivable Compulsory License Schemes. In those jurisdictions in
-        which the right to collect royalties through any statutory or
-        compulsory licensing scheme cannot be waived, the Licensor
-        reserves the exclusive right to collect such royalties for any
-        exercise by You of the rights granted under this License;
-    ii. Waivable Compulsory License Schemes. In those jurisdictions in
-        which the right to collect royalties through any statutory or
-        compulsory licensing scheme can be waived, the Licensor waives the
-        exclusive right to collect such royalties for any exercise by You
-        of the rights granted under this License; and,
-   iii. Voluntary License Schemes. The Licensor waives the right to
-        collect royalties, whether individually or, in the event that the
-        Licensor is a member of a collecting society that administers
-        voluntary licensing schemes, via that society, from any exercise
-        by You of the rights granted under this License.
-
-The above rights may be exercised in all media and formats whether now
-known or hereafter devised. The above rights include the right to make
-such modifications as are technically necessary to exercise the rights in
-other media and formats. Subject to Section 8(f), all rights not expressly
-granted by Licensor are hereby reserved.
-
-4. Restrictions. The license granted in Section 3 above is expressly made
-subject to and limited by the following restrictions:
-
- a. You may Distribute or Publicly Perform the Work only under the terms
-    of this License. You must include a copy of, or the Uniform Resource
-    Identifier (URI) for, this License with every copy of the Work You
-    Distribute or Publicly Perform. You may not offer or impose any terms
-    on the Work that restrict the terms of this License or the ability of
-    the recipient of the Work to exercise the rights granted to that
-    recipient under the terms of the License. You may not sublicense the
-    Work. You must keep intact all notices that refer to this License and
-    to the disclaimer of warranties with every copy of the Work You
-    Distribute or Publicly Perform. When You Distribute or Publicly
-    Perform the Work, You may not impose any effective technological
-    measures on the Work that restrict the ability of a recipient of the
-    Work from You to exercise the rights granted to that recipient under
-    the terms of the License. This Section 4(a) applies to the Work as
-    incorporated in a Collection, but this does not require the Collection
-    apart from the Work itself to be made subject to the terms of this
-    License. If You create a Collection, upon notice from any Licensor You
-    must, to the extent practicable, remove from the Collection any credit
-    as required by Section 4(b), as requested. If You create an
-    Adaptation, upon notice from any Licensor You must, to the extent
-    practicable, remove from the Adaptation any credit as required by
-    Section 4(b), as requested.
- b. If You Distribute, or Publicly Perform the Work or any Adaptations or
-    Collections, You must, unless a request has been made pursuant to
-    Section 4(a), keep intact all copyright notices for the Work and
-    provide, reasonable to the medium or means You are utilizing: (i) the
-    name of the Original Author (or pseudonym, if applicable) if supplied,
-    and/or if the Original Author and/or Licensor designate another party
-    or parties (e.g., a sponsor institute, publishing entity, journal) for
-    attribution ("Attribution Parties") in Licensor's copyright notice,
-    terms of service or by other reasonable means, the name of such party
-    or parties; (ii) the title of the Work if supplied; (iii) to the
-    extent reasonably practicable, the URI, if any, that Licensor
-    specifies to be associated with the Work, unless such URI does not
-    refer to the copyright notice or licensing information for the Work;
-    and (iv) , consistent with Section 3(b), in the case of an Adaptation,
-    a credit identifying the use of the Work in the Adaptation (e.g.,
-    "French translation of the Work by Original Author," or "Screenplay
-    based on original Work by Original Author"). The credit required by
-    this Section 4 (b) may be implemented in any reasonable manner;
-    provided, however, that in the case of a Adaptation or Collection, at
-    a minimum such credit will appear, if a credit for all contributing
-    authors of the Adaptation or Collection appears, then as part of these
-    credits and in a manner at least as prominent as the credits for the
-    other contributing authors. For the avoidance of doubt, You may only
-    use the credit required by this Section for the purpose of attribution
-    in the manner set out above and, by exercising Your rights under this
-    License, You may not implicitly or explicitly assert or imply any
-    connection with, sponsorship or endorsement by the Original Author,
-    Licensor and/or Attribution Parties, as appropriate, of You or Your
-    use of the Work, without the separate, express prior written
-    permission of the Original Author, Licensor and/or Attribution
-    Parties.
- c. Except as otherwise agreed in writing by the Licensor or as may be
-    otherwise permitted by applicable law, if You Reproduce, Distribute or
-    Publicly Perform the Work either by itself or as part of any
-    Adaptations or Collections, You must not distort, mutilate, modify or
-    take other derogatory action in relation to the Work which would be
-    prejudicial to the Original Author's honor or reputation. Licensor
-    agrees that in those jurisdictions (e.g. Japan), in which any exercise
-    of the right granted in Section 3(b) of this License (the right to
-    make Adaptations) would be deemed to be a distortion, mutilation,
-    modification or other derogatory action prejudicial to the Original
-    Author's honor and reputation, the Licensor will waive or not assert,
-    as appropriate, this Section, to the fullest extent permitted by the
-    applicable national law, to enable You to reasonably exercise Your
-    right under Section 3(b) of this License (right to make Adaptations)
-    but not otherwise.
-
-5. Representations, Warranties and Disclaimer
-
-UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
-OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
-KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
-INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
-FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
-LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
-WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION
-OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
-
-6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
-LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
-ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
-ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
-BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
-
-7. Termination
-
- a. This License and the rights granted hereunder will terminate
-    automatically upon any breach by You of the terms of this License.
-    Individuals or entities who have received Adaptations or Collections
-    from You under this License, however, will not have their licenses
-    terminated provided such individuals or entities remain in full
-    compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
-    survive any termination of this License.
- b. Subject to the above terms and conditions, the license granted here is
-    perpetual (for the duration of the applicable copyright in the Work).
-    Notwithstanding the above, Licensor reserves the right to release the
-    Work under different license terms or to stop distributing the Work at
-    any time; provided, however that any such election will not serve to
-    withdraw this License (or any other license that has been, or is
-    required to be, granted under the terms of this License), and this
-    License will continue in full force and effect unless terminated as
-    stated above.
-
-8. Miscellaneous
-
- a. Each time You Distribute or Publicly Perform the Work or a Collection,
-    the Licensor offers to the recipient a license to the Work on the same
-    terms and conditions as the license granted to You under this License.
- b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
-    offers to the recipient a license to the original Work on the same
-    terms and conditions as the license granted to You under this License.
- c. If any provision of this License is invalid or unenforceable under
-    applicable law, it shall not affect the validity or enforceability of
-    the remainder of the terms of this License, and without further action
-    by the parties to this agreement, such provision shall be reformed to
-    the minimum extent necessary to make such provision valid and
-    enforceable.
- d. No term or provision of this License shall be deemed waived and no
-    breach consented to unless such waiver or consent shall be in writing
-    and signed by the party to be charged with such waiver or consent.
- e. This License constitutes the entire agreement between the parties with
-    respect to the Work licensed here. There are no understandings,
-    agreements or representations with respect to the Work not specified
-    here. Licensor shall not be bound by any additional provisions that
-    may appear in any communication from You. This License may not be
-    modified without the mutual written agreement of the Licensor and You.
- f. The rights granted under, and the subject matter referenced, in this
-    License were drafted utilizing the terminology of the Berne Convention
-    for the Protection of Literary and Artistic Works (as amended on
-    September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
-    Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996
-    and the Universal Copyright Convention (as revised on July 24, 1971).
-    These rights and subject matter take effect in the relevant
-    jurisdiction in which the License terms are sought to be enforced
-    according to the corresponding provisions of the implementation of
-    those treaty provisions in the applicable national law. If the
-    standard suite of rights granted under applicable copyright law
-    includes additional rights not granted under this License, such
-    additional rights are deemed to be included in the License; this
-    License is not intended to restrict the license of any rights under
-    applicable law.

-   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
-
-   1. Definitions.

-      source, and configuration files.
-
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain
-      separable from, or merely link (or bind by name) to the interfaces of,
-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of
-      the copyright owner. For the purposes of this definition, "submitted"
-      means any form of electronic, verbal, or written communication sent
-      to the Licensor or its representatives, including but not limited to
-      communication on electronic mailing lists, source code control systems,
-      and issue tracking systems that are managed by, or on behalf of, the
-      Licensor for the purpose of discussing and improving the Work, but
-      excluding communication that is conspicuously marked or otherwise
-      designated in writing by the copyright owner as "Not a Contribution."
-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
-
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
