- `figcraft-cli mcp --automation-read-root DIR --automation-write-root DIR` (each repeatable, `--flag=DIR` works too). When either is given, every file an agent's tool call reads must lie inside a read root or a write root, and every file it writes inside a write root. Anything else is an ordinary tool error (`automation path rejected: … is outside the folders that may be written: …`); nothing is written and the server keeps serving. Without the flags nothing changes.
- The desktop app takes the same flags (`figcraft --control PORT --automation-read-root DIR …`) and confines every control request and every frame of every window to them, so `figcraft-cli mcp --attach` drives a confined app. `--attach` together with the flags is a usage error, because the app runs the commands and only the app can confine them.
- New engine module `crates/engine/src/file_access.rs`: `Roots` (resolution and comparison), a thread-scoped `confined(roots, f)`, and the file primitives (`read`, `read_capped`, `open`, `metadata`, `read_dir`, `write` (atomic), `create_dir_all`, `exists`, `is_dir`). Every engine file access now goes through it. `crates/engine/clippy.toml` denies `std::fs::*`, `File::open/create`, `OpenOptions::open`, `Path::exists/is_file/is_dir/metadata/read_dir/canonicalize` and `figcraft_format::{write_file_atomic, save_file, load_file}` everywhere else in the engine, so a command added later is confined without a check of its own.
- `ui.screenshot` and `ui.render` return the PNG as base64 `data` when no `path` is given (before, `ui.screenshot` wrote `figcraft-screenshot.png` in the working directory and `ui.render` required a path). The attached MCP backend uses that, so it no longer writes and deletes temporary PNGs, and a confined app needs no exemption for them.
- `initialize`'s `instructions` name the folders the agent may read and write.
- `figcraft-cli` options may be given more than once (`Args::values`); single-valued options keep the last value, as before.
- Docs: `docs/mcp.md` › Confining file access (options, semantics, coverage, resolution, limits), `docs/control-protocol.md` › Confining file access and the optional `path` of `ui.screenshot` / `ui.render`, `docs/cli.md`, `figcraft-cli --help`, and the Automation line plus a revision row in `docs/target-app-parity.md`.
Fixes#715, fixes#481.
The pages list took a fixed 40% of the left panel (#272). The line under
it now drags to make the list taller or shorter: at least three rows, and
always leaving the layers their header and three rows. A double-click puts
back the default. The main window keeps the height in the preferences, as
it does the panel widths, saved once the drag is over.

`drain_hidden` answered only requests for the main window, and only
while that window was hidden. A request addressed to another window
(`window.new`, `window` param) that is minimised or covered still waited
for that window's frame and timed out after 60 s, whether the main
window was on screen or not. An agent that works in its own window lost
it as soon as the window went behind others or to another Space.
`drain_hidden` now looks at the target window of each request: if that
window is hidden (`ViewportInfo::visible() == Some(false)` for its
viewport) and the method needs no frame, it is answered from the main
window's logic with the target window's state swapped in, as while it
draws, so it acts on that window's file. `draw` and the new
`windows::as_window` share the swap (`enter`, `adopt`, `leave`). The
main window's logic runs on every request (the control server asks for
a repaint), so this works while the main window is on screen too. What
needs a frame keeps waiting, as before; a request for a window that
doesn't exist is an error at once instead of waiting for a frame.
View > Full screen (`view.fullscreen {on?}`, F11 on Windows and Linux,
Ctrl+Cmd+F on macOS) makes the window fill the screen, taskbar included,
and leaves it again. FigCraft's own menu item, translated in every catalog.
Tests: the key and the command toggle the window, junk parameters are
ignored; the shortcut table pins the new binding (49 pinned).

- Cursors: the engine names a cursor for every tool, modifier and hover
target (rotate turned to its corner, pen states, eyedropper, comment,
copy on Alt, not-allowed while an instance refuses the edit); the UI shows
the system's or draws its own; guides and handles keep their cursors;
ui.inspect reports it.
- Panels: each edge drags its panel within limits, a double-click resets,
widths are per window and kept in the preferences (view.panelWidths); a
small window keeps its canvas.
- Outline mode: Include hidden layers and Include object bounds
(view.outlinesHiddenLayers, view.outlinesObjectBounds), drawn and
clickable; light lines on a dark page; check marks in the View menu.
- A file or page made in the dark theme has a #1E1E1E page (sessions
without an interface keep #F5F5F5); text drawn on a dark page is white.
- Tests for Enter and Escape on a selected text.
Found and fixed in a Windows pass of everyday workflows: unsaved documents are now copied in the background (at most every 10 s) and offered back after a crash or forced quit (file.recover); Ctrl+arrow / Ctrl+Backspace / Ctrl+Delete text motion follows Windows and Linux conventions (keymap::text_motion); number-field scrubbing keeps its value; typing in a Tab-focused field works; default linear gradients and their handles behave; Escape closes dialogs without deselecting; clipped panel hints wrap; the unsaved-changes dialog is translated.
File > New window, Open in new window on a tab, and dragging a tab out open files in separate OS windows (egui deferred viewports, redrawn only when needed), sharing one session, preferences, libraries and clipboard. Closing a window asks about unsaved files (the main window now asks too); closing the last window quits. window.new / window.list / window.focus and per-window screenshots for the control channel and attached MCP. The browser keeps one window.
