One keymap (figcraft_engine::keymap) now holds every default shortcut,
grouped like the public shortcut reference, with macOS and Windows/Linux
keys where they differ and canvas / text-editing contexts. The menus,
canvas, control channel, MCP key tool and Keyboard shortcuts panel all
resolve keys there; the catalog keeps only the menu tree.
- Fixed: Cmd/Ctrl+K made a link on the canvas (now Actions; link only
while typing), Shift+1 and Ctrl+Shift+? never matched (key names are
normalised), mask / bring to front / send to back / tidy up / layout
grids on Windows and Linux, distribute on macOS, outlines (Shift+Cmd+O),
pixel grid (Cmd+'), paint bucket B in vector edit mode.
- Added: Cmd/Ctrl+/, + and - zoom, Cmd/Ctrl+0, hold Z zoom tool
(view.zoomAt), two quick digits for exact opacity (object.opacityKeys),
Alt+Shift+U/S/I/E booleans, Alt+/ and Shift+/ remove fill/stroke, pixel
preview, Shift+E / Shift+D / Shift+Cmd+\ panel keys, Ctrl+Tab between
files (doc.nextTab / doc.previousTab), Shift+I, Shift+Space preview,
Home/End frames, Ctrl+C pick colour on macOS.
- Keyboard shortcuts panel: docked at the bottom, a tab per group, search,
keycaps per platform; tooltips show the platform's keys.

* M4: arc handles on the canvas
A selected ellipse shows its arc handles with the Move tool, as public
documentation of Figma-class tools describes them:
- Sweep, inside the right edge on the centre line: dragged round the ellipse
it opens an arc (positive up, negative down, continuous through a full
turn) and closes again back at the start.
- Start (a dot inside), once there is an arc: turns the arc, keeping its sweep.
- Ratio, at the centre or the inner edge halfway round a ring: drags out to a
ring, and into the gap to show the other part.
- Shift snaps angles to 15 degree steps and the ratio to 5% steps; a live
readout (Sweep 75%, Start 90 degrees, Ratio 40%) shows beside the handle.
- Rotated and flipped ellipses, any zoom; hidden under 40 px on screen.
One undo step per drag through node.set's arcStart/arcSweep/arcInner;
Escape cancels.
The geometry lives in crates/engine/src/arc_handles.rs (tests in
arc_handles_tests.rs); the gesture in tools.rs; ui.inspect / inspect_ui list
tool.arcHandles and the overlay's arc readout. Docs, README and ROADMAP
updated.

- Expressions as text: Expr::parse (variables by name, literals, and/or/not, comparisons,
arithmetic, text joins) with plain-English errors, type checks for conditions and set variable
values; display reads back as the same expression.
- New commands proto.action.add/set/remove/move and proto.conditional.addBlock/setCondition/
removeBlock edit single actions by path, inside conditionals too; `expression` text accepted by
these and proto.interaction.add/set.
- Interaction editor: an action list (open, move, remove, add), Add action > Conditional, if /
else if / else blocks with a condition builder (variable picker, operator, value or variable) or
an expression field with inline errors, nested actions, set variable expressions.
- Presenter: hotspot hints toggle (Options menu, proto.presentOptions {hotspotHints}), hotspots from
the engine (proto_run::hotspots) and in ui.inspect; an Inspect panel showing the hovered layer's
properties ({inspect}).
- Fields keep the keyboard on the click that opens them, and the Enter that commits a field no
longer reaches the shortcuts.

* M6: Dev Mode component code, annotations and ready for dev
- Component code: React (new), SwiftUI and Compose write components as reusable
units whose component properties are parameters (variant unions/enums,
boolean flags, text strings, instance swaps as views, slots as optional
content); variant sets share one definition (React: data-* rules for the
other variants); instances are calls passing only the values they change.
Escaped, unique identifiers. `inspect.componentCode` returns the parts.
- Annotations: notes with pinned properties on any layer, saved with the file
(left out when empty), undoable `annotation.add/edit/remove`, `annotation.list`
with live values; drawn as callouts on the canvas in the Inspect tab and
edited in its Annotations section. Instances keep their own annotations.
- Ready for dev: `inspect.readyForDev` lists frames and sections by handoff
status; the Inspect tab sets the status and lists them with a filter.
- Shared widgets: a multi-line field and the status dropdown are reused.

- Arrow keys move auto layout children one place: along the flow (past hidden and
absolute siblings), between wrapped rows, to the neighbouring grid cell, and into
the neighbouring nested auto layout frame; no undo step when nothing moves.
- Sections: section.toggleContents (hide contents), object.wrapInSection, frames in
sections are top-level frames (labels, flows, navigation, PDF export), navigating
to a section shows its frame shown last.
- Ready for dev turns "Changed" when contents are edited; dev.resolveChange with a reason.

Measuring (Alt/Option): distances from the selection to the hovered layer,
its parent (over the selection itself or empty space) and ruler guides;
Cmd+Alt for nested layers; containment both ways, overlaps between matching
edges, gaps with dashed extension lines; rotated layers and several selected
layers by their bounds; the measured box outlined. Alt while dragging shows
live distances to the neighbours (or the parent's edges); Shift+Alt reads out
an auto layout frame's padding and gaps. Labels are placed so they never
overlap each other or the size label and stay the same size at every zoom.
Commands: measure.distances, measure.padding.
Scale tool (K) canvas handles: one factor about the Scale panel's anchor
(tool.scaleAnchor, shared by the panel and the canvas; the opposite handle when
the anchor is on the side being dragged), Alt from the centre, flips past the
pivot, rotated layers and lines along their own axes, one undo step per drag,
a live factor in the size label and the pivot marked. scale_node now also
scales min/max sizes, layout grids, guides, fixed grid tracks, tiled images,
paragraph indent and run letter spacing.
Selection: Cmd/Ctrl-marquee selects nested layers, Shift-marquee toggles,
the context menu's Select layer lists every layer under the click
(select.layersAt), outlines are purple for every layer inside components and
instances, hover outlines show with the Scale tool too. Fixed marquees
selecting layers that only overlapped the marquee on one axis.

The Start point and End point menus draw each line end beside its name (none, round, square, line
arrow, triangle, reversed triangle, circle, diamond; mirrored for start points). `ui.input` takes
`{scroll: [dx, dy]}` mouse-wheel events, so scrolled panels can be driven and checked.

Pins follow their layers (to other pages too) and stay where they were
when the layer is deleted, re-pinned to the nearest surviving parent;
your pins drag onto another frame; crowded pins cluster when zoomed out
and a click zooms them apart; Shift+C shows or hides them.
Threads: edit and delete your own messages (marked edited), emoji
reactions, @mentions with a picker of the names used in the file (your
name from Preferences), read/unread state per name, and Copy link
(figcraft://comment/<id>; pasting it or comment.open goes to the page,
zooms to the frame and opens the thread).
Comments panel: search (text, names, frame), filters (open, resolved,
yours, unread), sort by date or page, each thread's frame and page,
Up/Down to step through threads. The presenter shows the presented
frame's comments (Comments button or Shift+C) to read and reply.
New commands: comment.react, comment.markRead, comment.open,
comment.next, comment.zoom, comment.link, comment.people,
pref.userName; comment.list gains filter/sort/query/frame, comment.move
re-pins. Old files load unchanged (the first message stays on the
comment; missing read state counts as read).

Right-to-left and mixed-direction names in the panels: layers, pages,
Assets, tab titles, the file header and canvas frame titles show in
visual order (Unicode bidi, joined Arabic letters, mirrored brackets),
elided at their end (the left end of a right-to-left name). egui shapes
each font run itself, so shown names are laid out a cluster at a time.
Rename fields keep egui's editing and draw the shown text over it: the
caret, selection, clicks, drags and arrow keys follow what's on screen.
System fonts are added for scripts the built-in UI fonts lack.
The Typography section's text style browser: list and grid views with
each style in its own font, search, folders, this file's and enabled
libraries' styles, apply, detach, edit the typography, create from the
selected chars, hover to preview on the canvas, and "Mixed" when the
chars use several styles. Text styles now link chars (style_id on text
styles), so a range can take a style; editing what a style sets
unlinks the chars edited; files from before link on open.
Live text previews (text.preview / text.endPreview): a hovered text
style, font style or named instance and a dragged axis slider show on
the canvas without an undo step; release commits one step, Escape
cancels. ui.input sends raw window input over the control channel.
Visual QA: list markers keep the paragraph's font, renames start with
the name selected and centred, Max lines shows while truncating.

- Responsive presentation: `proto.settings {responsive}` (saved in the
page's prototype settings). The player resizes the presented frame to the
device's screen, or without a device to its whole area at 100%, and lays
it out again exactly as an editor resize does (constraints, auto layout,
text; an axis the frame hugs keeps hugging), live as the window, device or
file change. The player keeps its design document and lays the screen out
from it each time (`cmd::proto::respond`). In the presenter's Options menu
(Responsive beside the size options, or Responsive / Fixed size on a
device) and the Prototype panel.
- Device colours: each device model lists its colour variants
(`proto.settings {color}`), drawn in code as the body's band round black
glass; screen corners are masked exactly. Colour picker with swatches in
the Prototype panel.
- Custom size: a bare screen of any size (`proto.settings {width, height}`
picks it), W/H fields and a swap button in the Prototype panel, imported
from REST `CUSTOM` devices.
- Library collections in the Design panel's Variable modes section, under
their library's name (`library.setVariableMode`; copies whose library
isn't read stay listed).
- Flow descriptions in the presenter's flow picker (and its hover) and under
each flow in the Prototype panel.
- Tests in new modules: engine proto_responsive_tests, ui-egui
proto_responsive_tests; REST device test updated.

PDF export
- Vector masks clip to the mask's outline, luminance masks are luminosity
soft masks (alpha masks as before).
- Background blur: the backdrop the page draws under the layer is rendered,
blurred and cut to its shape, under the layer's vector content.
- Text hyperlinks become clickable link annotations (one per line and link).
- Frames-to-PDF shares one path (`frames_pdf`): sRGB conversion for Display
P3 files, hidden frames left out, the file name as the PDF title.
- `figcraft-cli export -o x.pdf` and `convert x.figcraft x.pdf` write the
page's frames one PDF page each.
- Tests: mask types, backdrops, links, image deduplication, page sizes in
points, hostile inputs; CLI end to end. Checked by rendering the PDFs back
to PNG and diffing against the PNG export.
Prototyping
- Model: conditional actions (if / else if / else blocks), set variable mode,
and expressions (literals, variable references, + - * /, comparisons,
and/or/not, negate) for set-variable values and conditions; walk helpers
for nested actions (remap on paste, colours, destination checks, library
copies and pruning, canvas connections).
- REST import maps CONDITIONAL, SET_VARIABLE_MODE and SET_VARIABLE with
variable references and EXPRESSION values; unsupported functions (mode
lookups) skip the action with a warning.
- The presenter runs them in order (`figcraft_engine::proto_run`); the
Prototype panel summarises conditionals, edits set-variable-mode, and
`ui.set {protoEditor}` opens an interaction's editor.

A stroke can carry a width profile: widths at positions along the path
(each subpath by length), interpolated smoothly (monotone cubic).
- doc: WidthProfile / WidthPoint / WidthPreset (uniform, wedge, taper both
ends, eye, rounded, pinch) on StrokeProps, serde-defaulted so older files
load; paint reach and hit testing follow the widest point.
- pathops: path measuring by length and the variable outline (offset along
the normals, round/miter/bevel joins, caps, dashes keep their width,
Inside/Outside clip as before; bounded samples and dashes, uniform
fallback). Canvas, PNG, SVG (filled outline), PDF and outline stroke use it.
- engine: stroke.widthProfile {preset | points}, node.set widthProfile,
inspect output; the Variable width tool (Shift+W) in vector edit mode:
drag the path to add a width point, slide points, drag their handles,
Delete removes the selected one; vector.edit.widthPoint add/set/remove.
Every gesture is one undo step.
- UI: width profile dropdown with previews drawn in code and a flip button
in the stroke settings; the tool in the edit toolbar (new icon drawn in
code); width handles and a hover preview on the canvas; Position/Width
fields for the selected width point.
- Tests: profile maths, outlines, render regressions, tool gestures,
commands, exports and junk sweeps. ROADMAP, README, docs updated.

- Device rotation: phones and tablets turn to landscape (`proto.settings {rotation}`), saved in
the file and imported from REST files (`CCW_90`); the presenter and the preview pane size the
screen to the turned device and draw its body turned. A rotate toggle sits beside the device
picker in the Prototype panel.
- Presentation options: fit, fit width, fill and 100% (`proto.presentOptions {scale?,
deviceFrame?}`, an Options menu in the presenter, Z cycles them, R restarts), the device frame
shown or hidden, kept between presentations; what overflows the window pans by wheel or drag.
Presenter textures are capped to the GPU's limit (big frames at 100% no longer overflow it).
- Scroll momentum: drags fling and slow down exactly per frame-rate-independent sub-steps, the
wheel coasts after it stops, a drag past the ends stretches and springs back; repaints only
while moving, a press catches a fling.
- Variable modes in the Design panel: frames pick a mode per multi-mode collection, or Auto
(inherited); `variable.setMode {mode: null}` sets Auto.
- Tests in new modules (engine proto_present_tests, UI present_view_tests); docs and ROADMAP.

Every UI icon redrawn on a strict 16 px grid: strokes on pixel centres, fills on pixel edges, and
consistent proportions. Painting snaps the glyph to the pixel grid, scales by whole steps above
16 px, hints straight strokes below it, and keeps strokes one physical pixel wide, so icons stay
sharp at every size and display scale. Concave fills (the move cursor) are triangulated instead of
drawn as convex polygons, which broke them. Icon buttons paint their glyph at its native 16 px.
Redrawn: hand, home, move cursor, comment, moon, undo/redo, rotate/reset, link, corner radius,
flip, eye, lock, clock and the rest of the set. `Icon::ALL` lists every icon; the control channel's
`ui.set {iconGallery: true}` shows them all at 12/16/24/32 px for review.

Publishing a library now includes the file's variable collections (modes,
aliases, scopes), versioned per variable and collection; variables hidden
from publishing stay out unless a published variable aliases them or a
published component binds them. Files using the library see its
collections read-only in the Variables editor and the variable pickers;
binding, aliasing or setting a collection's mode copies the variables in
as read-only linked copies, library components keep their bindings, and
"Library updates available" covers changed variables (bound layers follow).
New commands: library.importVariable, library.bindVariable,
library.aliasVariable, library.setVariableMode; variable.update takes
hiddenFromPublishing.

Slots: a frame of a main component becomes a slot property
(component.makeSlot / removeSlot, preferred components, type "slot" in
component.properties). Instances show the main's default content until
the slot is edited; from then on its layers are the instance's own
(override group "slot"): free to add, remove and reorder, kept across
main updates, variant switches, copy/paste and detach, and instances
placed there stand alone. instance.slotInsert fills a slot,
instance.resetSlot brings the default content back. Structure
protection allows edits inside slots only; drops from the Assets panel,
canvas drags, drawing and paste land in slots. UI: slot icon in the
layers panel, dashed outlines and labels on the canvas, slot property
rows with a fill menu in the properties panel, Make/Remove slot on
frames inside a main.
Nested overrides: overrides inside a nested instance survive the main
moving it into another frame (layers matched by source alone when
unique); a nested instance copied out of an instance is re-linked to
its own main with its look kept (values set by component properties
aren't overrides); plain layers copied out of instances stop mirroring
them; canvas drags can no longer pull layers out of an instance or
reorder its auto layout children. Tests for swaps, variant switches,
main restructuring, detach and copy/paste.

* M3: colour profiles: sRGB or Display P3 per file, convert or keep values, tagged exports
- color: ColorProfile (srgb, displayP3) with conversions derived from the primaries (shared D65
white and sRGB curve; out-of-gamut channels clip), table-driven pixel conversion, a generated
ICC v4 matrix/TRC profile and PNG cICP code points.
- doc: Document.color_profile (serde default sRGB, written only when set); every colour value
(paints, text runs, effects, grids, page and prototype backgrounds, overlay backdrops, styles,
colour variables, document colours) can be mapped; set_color_profile converts or reinterprets.
- engine: file.colorProfile {profile?, convert?} (File > Color profile...; without a profile it
opens the dialog); document.inspect reports colorProfile.
- render: images are taken as sRGB and managed into the file's space; encode_export tags PNG
(sRGB chunk, or iCCP + cICP for Display P3) and embeds the ICC profile in Display P3 JPG/WebP;
SVG and PDF export Display P3 files converted to sRGB. The CLI exports the same way.
- ui: Color profile dialog (keep appearance / keep values) and a Color profile row on the page
panel; the canvas, presenter, thumbnails, swatches and colour picker show a Display P3 file's
colours converted to the screen's sRGB, and Copy as PNG converts too.

* M3: image adjustment presets: built-in, saved in the file, reset
- color: ImageFilters::PRESETS (Vivid, Muted, Warm, Cool, Black & white, Fade, Reset), lookup by
id or label, and sanitized values.
- doc: Document.image_presets (name + adjustments; written only when there are some).
- engine: image.adjust {ids?, target?, index?, preset?, filters?} sets the adjustments of image
paints from a preset (built-in or saved) with values on top, one undo step; image.savePreset,
image.deletePreset and image.presets.
- ui: the colour picker's image section gets a presets menu named after the preset in effect
("Custom" otherwise), saved presets with delete, "Save as preset...", a Reset button, and
aligned adjustment sliders.

* M3: style picker: search, folders, list or swatch grid, edit, create, detach
The Fill, Stroke, Effects and Layout grid sections' Styles button opens a popover laid out like
the variable picker (crates/ui-egui/src/style_picker.rs):
- search over style names; styles grouped by the folders of their `/`-separated names, which
collapse (searching opens them); colour styles as a list or a grid of swatches;
- click applies, a check marks the applied style; the row's edit button (or a right-click) edits
the name, description and values: colour style paints open the colour picker on the style,
effect and grid styles update from the selection; delete;
- `+` creates a style from the selection's current values and opens it for naming; detach;
- colour slots still list colour variables to bind;
- the applied style chip opens the picker; new icons Adjust, ViewList, ViewGrid (drawn in code);
- control channel: ui.set {stylePicker, stylePickerEdit, stylePickerView}.

* M5: scrolling inside device frames and a prototype preview pane
On a device, the presented top-level frame is sized to the device's screen:
what doesn't fit is clipped, or scrolls (wheel and drag) when its overflow
allows it. Fixed layers stay on screen, pinned to the edges their
constraints name; "Scroll to" moves every scrolling frame around the layer;
navigating starts at the top unless the new "Preserve scroll position"
option keeps it.
The preview pane is a resizable window over the canvas running the same
player (present.rs now shares layout, drawing and input between the
full-window presenter and the pane). It follows edits live, keeps the
current screen while it exists, shows a newly selected top-level frame, and
takes the keys its prototype uses only while hovered. Opened from the play
menu, the Prototype tab (flows, settings, frame) and `proto.preview
{start?}` / `proto.closePreview`; the control channel gets `ui.set
{preview, presentScroll}` and the player's state in `ui.inspect`.
Alt+Cmd+Enter now presents.

* M6: REST import of prototypes and variables; export panel polish
REST API file JSON import now brings prototyping and variables along:
- interactions: on click/hover/press/drag, after delay, mouse enter/leave/down/up and key
triggers; navigate, open/swap/close overlay, back, scroll to, change to, open link and set
variable actions (lone unconditional blocks inlined); dissolve, smart animate, move, push and
slide transitions with easing incl. custom bezier and spring; the legacy transitionNodeID
- flow starting points (and the deprecated start node), overflowDirection, scrollBehavior,
prototypeDevice and prototype background
- the local variables response (collections, modes with the default first, values, aliases,
scopes), passed as `variables` to file.open / file.import (object, JSON text or path), found
next to the file (<name>.variables.json / variables.json) or embedded; boundVariables, paint
and text style bindings and explicitVariableModes map onto the fields variable.bind uses
- file.import appends variables, flows and prototype settings with the pages
- unsupported parts (video, gamepad, conditionals, variable modes, library variables) warn
Export panel: rows with a typed or preset size (2x, 512w, 512h), suffix and all five formats
through the new export.update command; export.add steps up (1x, 2x @2x, ...); a preview;
"Export N layers" through the new file.exportLayers (one file per setting, unique safe names)
in the panel and the Export dialog; file.export takes `size`. MCP open_file/export pass the new
params.

* M6: Inspect tab: properties with styles and variables, redlines on hover (#41)
The Inspect tab lists the selected layer's properties for handoff:
layout (size, position from the parent, rotation, opacity, radius), auto
layout (direction, gap, padding, alignment), typography, fills, strokes
and effects, each with the style or variable it comes from. Clicking a
value copies it. With the Inspect tab open, hovering measures distances
from the selection without holding Alt.
New command inspect.properties returns the same groups for agents.

The selected shapes' outlines split the canvas into regions, computed as the faces of their
arrangement with linesweeper (curves kept, per-shape fill rules, holes and islands handled) and
cached per document version and selection.
- Engine: shapeBuilder.regions / merge / remove / mode commands, ToolId::ShapeBuilder and
tool.shapeBuilder (catalog: Tools > Shape builder, Shift+M). Merge makes one vector from the
picked regions styled like the top-most shape over the first; every shape covering a picked
region loses that area (becomes a vector, or is deleted when nothing is left). One gesture or
command is one undo step. Session::tool_key routes Enter (finish) and vector edit keys.
- Pathops: faces() (arrangement faces with their covering inputs) and union_faces().
- UI: region edges on the canvas, hovered/collected regions hatched (danger colour to remove),
no transform box while building, a toolbar pill with Merge/Remove modes, a hint and Done; shared
pill/tool-cell/divider/Done helpers; original merge/remove icons drawn in code.
- Tests: pathops faces; engine regions, merge, remove, curves, groups, rotation, pointer
click/drag/Alt, modes, Escape/Enter, cache, junk parameters and degenerate geometry.
- Docs: ROADMAP, README, docs/mcp.md, docs/control-protocol.md, docs/parity.md.

Large documents stay interactive: the canvas re-renders only what a pan uncovers or an edit
touches, the layers panel lays out only the rows in view, and per-frame work no longer walks the
whole page.
- Benchmark: `cargo xtask bench [SIZES]` builds synthetic pages (`figcraft_engine::synthetic`:
screens with an auto layout header, a card group, button instances and shapes/text) at
1k/10k/50k layers and prints engine/render timings (`figcraft-cli perf --layers 1000,10000`) and
headless whole-UI frame timings (an ignored ui-egui test).
- Retained canvas rendering (`figcraft_render::Retained`, used by the render worker): views snap
to whole device pixels, so a pan shifts the previous image in place and renders only the
uncovered strips; an edit renders only where changed layers were and are
(`Document::changed_ids` diffs the two versions skipping shared structure; ancestors that paint
from their children's pixels - booleans, effects, masks - count whole; background blur reach
and noise are allowed for). Zoom, page, options, font or page-level changes, or large changes,
render the whole view as before. `ui.inspect` reports `canvas.renderWork`.
- The texture image is converted on the render thread, not the UI thread.
- Layers panel: only visible rows are laid out (stable ids while scrolling); rows are cached per
document version, page, expanded set and filter.
- Frame labels and layout grids of off-screen top-level frames are skipped; the Prototype tab's
connection sources are cached per document version.
- Text: the layout cache keys by a cheap fingerprint confirmed by `TextData` equality (no Debug
formatting per lookup, 32k entries) and hands out shared layouts; a layout generation marks
renders stale when fonts arrive. Overflowing text is culled by its glyphs, so it no longer
vanishes while its box is off screen.
Before -> after (release, Windows, 1440x900 view, ms; 10k / 50k layers):
- move one layer, re-render @100%: 7.65 / 6.49 -> 0.18 / 0.81
- move one layer, re-render zoomed out: 11.95 / 24.10 -> 0.16 / 0.77
- pan 40 px @100%: 7.53 / 6.82 -> 0.69 / 0.81
- pan 40 px zoomed out: 12.07 / 24.30 -> 1.62 / 4.17
- full render @100% / zoomed to fit: 7.78 / 44.22 -> 6.56 / 38.83 (10k @100%, 50k fit)
- UI frame, every screen expanded in layers: 6.16 / 39.07 -> 0.24 / 0.57
- UI frame, scrolling that panel: 6.11 / 40.18 -> 0.43 / 0.40
- UI frame, layers filtered by name: 1.03 / 6.92 -> 0.17 / 0.36
- UI frame, Prototype tab: 0.89 / 6.45 -> 0.18 / 0.80
- UI frame, idle: 0.31 / 1.43 -> 0.11 / 0.39
Unchanged and within budget: single-layer edits through the engine ~0.01 ms, normalize after a
one-node edit < 0.01 ms, hit test 26 / 93 us. Left: save/load at 50k (~0.7 s each), zoomed-out
renders at 50k (~40 ms).
Tests: retained renders match full renders after pans, moves, recolours, hide/remove/add, undo,
masks, overflowing text, edits under a background blur and an inner-shadow/noise layer, a drop-
shadowed group, and a blur panned in from the view's edge; zoom/page/options/page background
render full; junk views don't panic. Layer-row and prototype-source caches follow edits, undo,
page switches, expansion and the filter. `changed_ids`, the text cache, and the perf CLI.

The Local variables window becomes a table editor: collections in a
sidebar, variables grouped by name with one value column per mode, typed
value cells (colour swatch + hex + alpha, number, string, boolean), alias
chips with a variable picker and detach, double-click rename, context
menus, and an Edit variable window for description and scopes.
New commands: variable.update (name, description, scopes),
variable.duplicate, variable.renameMode, variable.removeMode,
variable.renameCollection, variable.deleteCollection. variable.set
validates aliases (same type, no loops) and stores them by id; addMode
always picks a fresh mode id. Pickers offer only variables scoped to the
property. ui.set {variables} opens the editor on a collection.

- Gradient stops on the canvas: drag a stop along the gradient line, click the line to add a
stop (sampled colour), the selected stop is ringed and shared with the picker; Delete removes
it (two always stay).
- Colour picker value row: a model dropdown (Hex, RGB, HSL, HSB, CSS) with its fields and the
alpha field; scrubbing works on the numeric fields.
- "On this page" swatches: the page's most used solid colours (cached per document snapshot);
swatches set a solid colour or the selected gradient stop.
- New command `paint.documentColors {page?, limit?}`; control channel `ui.set {colorPicker}`.

- Arrow keys on children of an auto layout frame move them one place along the flow (Left/Up
earlier, Right/Down later; grids step by a row vertically); selected neighbours move as a
block and stop at the ends. Free layers still nudge.
- Cmd/Ctrl+arrows resize the selection by the nudge amount (Shift: big nudge), top-left fixed;
only the changed axis becomes Fixed. New command `transform.nudgeSize {dw, dh, big?}`.
- Control channel `ui.key` arrows with `cmd` resize too.

- Search toggle in the Layers header: a live filter that lists matching layers across the page.
- Shift-click selects the visible rows from the anchor to the clicked row (Cmd adds them to the
selection); Cmd-click toggles.
- The tree reveals a new selection once (expands its ancestors and scrolls its row into view),
so Collapse layers (Alt+L) and manual collapsing stick.
- Alt-click a disclosure triangle expands or collapses everything inside.
- Tab / Shift+Tab while renaming commits and renames the next / previous layer.
- Control channel: `ui.set {layerFilter, collapseLayers}`.

- Min/max width/height: the W/H sizing menus add min/max (at the current size) and remove them;
limit rows edit or add the missing bound. The layout clamps Fixed, Hug and Fill children and
the frame itself; a hugging text wider than its max width wraps at the max. min > max is kept
ordered by node.set (the other bound follows); in the layout min wins.
- Ignore auto layout (absolute position): a toggle in the Position section; the child stays
where it is, can't Fill, shows constraints and follows them when the auto layout frame resizes
(by hugging, filling or a direct resize).
- Text baseline alignment for horizontal layouts ("Align text baselines"; crossAlign baseline):
first-line baselines line up, other layers align to the top, nested auto layout frames use
their first child's baseline. Measure gains text_baseline.
- Grid auto layout: column/row tracks (fixed px, hug, fr fill) via columnTracks / rowTracks or
layout.setTrack, cells anchored by gridColumn / gridRow with gridColumnSpan / gridRowSpan,
auto placement in reading order, rows grow to fit, hugging grids size to their tracks.
Panel: column/row gap, track size rows, a child's cell and spans. Old files load unchanged
(serde defaults; missing tracks are 1fr).
- Canvas handles: wrapped-row gaps and grid column/row gaps are draggable; a selected grid's
tracks are outlined.
- The layout section moved from right.rs to layout_panel.rs; inspect reports min/max and a
grid child's resolved gridCell; docs list the new props.

- Edit-mode toolbar (Move V, Pen P, Bend hold Cmd, Paint bucket Shift+B, Lasso Q, Cut X, Done)
replaces the tools while a vector is edited.
- Pen in edit mode continues open ends, branches from any point (vector networks), adds points on
segments and closes paths into fill regions; dragging pulls out mirrored handles.
- Paint bucket fills or unfills any closed area: faces of the network (half-edge walk, nested
pieces become holes), with a hatched preview of the area under the pointer.
- Bend tool / Cmd: bend segments, pull handles out of a point, click a smooth point to sharpen it.
- Lasso and marquee point selection, segment selection (shift adds), cut at a segment or a point.
- Per-point handle mirroring (none / angle / angle and length, inferred for existing files),
Alt-drag breaks it; smooth/sharp points; join and merge selected points (Cmd+J, Shift+Cmd+J).
- Delete opens the path, Shift+Delete heals it; arrows nudge points; Cmd+A selects all points.
- Design panel shows the selected points' position, corner radius and mirroring.
- Every gesture is one undo step; edit mode ends when its layer is undone away.
- Paths that end on their start without a ClosePath (ellipse outlines) stay closed and filled.
- New commands (vector.edit.tool/pen/paint/cut/lasso/mirroring/smooth/position/nudge/connect/...)
for the CLI, control channel and MCP; docs updated.
- Clippy: simplify a few boolean expressions flagged by the current toolchain.
