   - Panels undock (#495): a dock tab, a panel icon or a popped-out panel's title dragged out of the dock floats that panel inside the window, and the strip right of the dock's tabs floats the whole tabbed group. A floating group moves by its title bar, a tab dragged out of it floats on its own, and dropped on another group's title bar or tabs it stacks with that group; dropped on the dock, which lights up under the pointer, its panels go back where they live (the tabbed group or the icon column), as its × and the panel menus' Float Panel / Dock Panel do (`window.panel.float`, `window.panel.dock`). The Tools panel floats by its title bar and docks again on the window's left edge. Floating groups stack into sets: dropped on the upper or lower half of another group (a line shows where), a group joins it right above or below it, and the set's groups stack top to bottom, each showing one panel, moving together by the top group's title bar, whose × docks them all; a group dragged by its tab strip leaves the set (`window.panel.float {below, above}`). A double-click on a tab collapses a floating group to its tabs (`collapsed`). Sets dropped on the left edge of the icon column or of another dock column dock as dock columns (a multi-column dock, `window.panel.dock {column}`), whose groups stack, tab and tear out as a floating set's do, and whose top strip floats the column again. Floating panels, their sets and the Tools panel's position are kept with the preferences and in user workspaces, and clamped into a smaller window. Not done: panels in separate OS windows, docking a panel into the default tabbed group it doesn't belong to, reordering tabs by dragging, collapsing a set or dock column to icons, dock columns right of the default dock, resizing floating panels and the groups of a set.
   - The dock's double arrow collapses Properties, Layers and Libraries to icons at the top of the icon column, popping out like the other icon panels, and expands them again (`window.collapseDock`, kept with the preferences and in saved workspaces). The icon column's own arrow (expanding the icon panels into a full column) is not done.
   - Czech render-site labels: desktop/web file filters, diagnostics, suggested preset names and contributor tooltips/plurals now use catalog lookups; gradients have Czech adjective agreement and printer marks have a separate context (PDF/Print and Summary). Search, Home, toolbar/panel tooltips and Preferences already look up their labels; new variable keys fall back to English in other languages. Evidence: `i18n::tests::czech_render_site_follow_up`, `dialogs::tests_modal::printer_mark_labels_are_distinct_from_language_names`; see [localization-parity.md](localization-parity.md).
-  - Localised UI: menus (in-window and native), panels, dialogs, toolbar and Preferences read from per-language catalogs (`crates/ui-egui/src/i18n`, see `docs/development.md`); Traditional Chinese (Taiwan), Simplified Chinese (mainland), Japanese, Korean, German, Spanish, French, Italian, Russian and Ukrainian ship complete, and Czech and Brazilian Portuguese cover every menu label (and more), with system-locale detection on macOS, Windows, Linux and the web (the browser's languages, or `?lang=`), a Language preference and, on macOS, a VectorCraft ▸ Language menu. Names are never translated (fonts and their styles, layers, artboards, saved presets, user libraries, custom workspaces, recent files, plug-ins).

   - Native macOS menu bar, vector tool cursors, a ⌘K command palette, middle-button panning with any tool. Native menus explicitly end tracking on command selection, outside window presses and Escape; menu updates wait until tracking ends, and a dismissing press never starts a canvas gesture (M14.8).
   - The macOS menu bar is built from the in-window menus (one model, `native_menu`) and laid out as a Mac app's: the VectorCraft menu holds About, Settings ▸ (each Preferences page, General… ⌘K), Language ▸, Appearance ▸ (UI brightness), Services, Hide VectorCraft ⌃⌘H (⌘H stays Hide Edges), Hide Others, Show All and Quit; Window gains Minimize ⌃⌘M, Zoom and Bring All to Front, and Help the system's search field. Its key equivalents go back to egui as key presses, so user shortcuts, focused text fields and the Type tool's input method behave as in the window, and nothing fires twice; enabled, check marks and labels update in place. `--in-window-menus` or `VECTORCRAFT_IN_WINDOW_MENUS=1` keeps the menus in the window; `ui.inspect` reports `nativeMenuBar`.
   - macOS: Finder opens every format File › Open reads with VectorCraft (double-click, Open With, a drop on the Dock icon, `open -a`), at launch or while it runs; the release and `cargo xtask bundle` apps share one `Info.plist` that declares those document types, owning only VectorCraft's own formats. The DMG opens on a designed Finder window, VectorCraft.app beside the `Applications` link over a background with the app icon (#493).
