Packaging: Windows MSI setup wizard (folder choice, progress, version, launch on finish)

Double-clicking the MSI now opens WixUI_InstallDir without the licence page: Welcome, install folder (remembered for upgrades in HKLM\Software\PhotoCraft\InstallDir), Ready, progress, and a Finish page with a ticked "Launch PhotoCraft" box (WixShellExec, unelevated). The pages name the full version, pre-release tag included (photocraft.en-us.wxl). package.ps1 draws the banner and side bitmaps from the app icon, so no WiX stock art ships. msiexec /qn still installs silently. The release and ARM64 workflows install the WiX UI and Util extensions; packaging-lint checks the .wxl. Ported from VectorCraft (storytold/vectorcraft@aa548d2).

 # AGENTS.md: guide for AI agents and contributors

-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/`.

-While iterating, run less and keep the full commands above as the final gate: `cargo test -p <crate> --lib --tests` skips the examples and doctests plain `cargo test` builds every time (ui-egui has 11 examples), and `cargo test -p <crate> --test <file>` runs one integration-test file. `cargo nextest run` runs tests in parallel across binaries; see `docs/development.md` › Faster test loops.

 **Test corpora.** Real-file corpora live in `corpus/` (gitignored, never committed), fetched at pinned commits and sha256-verified by `cargo xtask corpus --all`: our Photoshop-authored oracles from https://github.com/storytold/photocraft-corpus plus psd-tools, ag-psd and PngSuite from their upstreams. 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. Details: `docs/development.md` › Test corpora.

 Commands must **never panic** on bad input (Rule 9): every `run` closure and the code it calls returns `Err`, not a panic, for any params or document state. New commands come with a graceful-failure test (empty/out-of-range/wrong-type params → `Err`, not a crash).

-> **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).

-### 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.

-//! 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.

-//! 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.

-      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.

-### Export selected adjustment layers as a .cube LUT
-
-The engine command `file.export.colorLookupTables` creates a 3D LUT from an
-identity RGB lattice. It can export all visible top-level adjustment layers
-(the default), the current Layers panel selection, or a supplied list of
-adjustment layer IDs. The `scope` and `layers` parameters are mutually
-exclusive when `scope` is `selected`:
-
-```json
-{"size": 33, "scope": "selected", "path": "chosen-look.cube"}
-```
-
-For automation that does not use the Layers panel, supply `"layers": [10, 14]`
-instead. Input ID order does not change the final color look: adjustments are
-always baked in **document stacking order**, bottom to top. When `path` is
-omitted, the command returns the .cube text in `cube`; both forms return
-`size` and `layerCount`.
-
-Valid LUT dimensions are 2–129 (same maximum as PhotoCraft's LUT reader).
-Selected IDs must exist, be visible top-level adjustment layers, and contain
-no duplicates; invalid selections report an error rather than silently
-exporting a different look. Masks, vector masks and clipping are spatial
-operations and cannot be represented faithfully by a color-only LUT, so the
-baker omits them. Group-contained adjustments are not exported as independent
-layers because that would lose their group's blending semantics.

 Paths supplied to the current CLI are ordinary operating-system paths. The CLI does not restrict them to a workspace root. Batch output creates the requested output directory, and save operations may create parent directories. `batch` refuses an output directory that is its input directory (the results would replace the originals) unless `--in-place` is given. Run untrusted action files only in an appropriately isolated account or environment.

 CLI parsing reports malformed flags and JSON as errors, and a flag the subcommand doesn't take (a typo such as `--fromat`) is a usage error (exit status 2) rather than being ignored. It is not a security policy layer. Engine commands remain responsible for validating their own parameters.

 Every route that writes a document to a flat format (Save As, the CLI, MCP `doc_export`, Layers to Files, Layer › Export As) flattens it the same way:

 - Formats without transparency (JPEG, Radiance HDR) get the image composited over white, as Export As and Quick Export do; in CMYK, white is no ink.
- Formats that can't embed an ICC profile (GIF, BMP, TGA, QOI, ICO, Netpbm/PFM) get RGB documents in another profile (linear light, Display P3, …) converted to sRGB through the colour engine (perceptual intent), since an untagged file is read as sRGB. OpenEXR and Radiance HDR get linear sRGB instead (linear gray for a grayscale OpenEXR), which is how they are tagged when opened.
- TGA, as Photoshop's Targa: an RGB Targa is 24 or 32 bits per pixel. Save As and Save a Copy ask (Targa Options, starting at 32 with an alpha channel, else 24); Export As has a Resolution choice (Auto, 24 or 32 bits/pixel); scripts pass `tgaBits` (`--tga-bits` on the CLI). At 32 bits the document's alpha channel is the file's alpha when it has exactly one (spot channels don't count; with several, none is used), and the colours are written exactly, never premultiplied or cleared where the alpha is 0, so a game texture's mask and its colours both survive. Without a usable alpha channel the layers' transparency is the alpha (opaque without any). 24 bits write no alpha, compositing transparency over white. Without a choice: 32 with an alpha channel or transparency, else 24. A 32-bit Targa opens as an opaque Background with its alpha as "Alpha 1", so it round-trips. Grayscale Targas are 8-bit.
