Corner widgets only ever showed on live rectangles: CornerWidgets::of bailed
out unless the selection's live shape was LiveShape::Rectangle, and
object.setLiveShape only edited rectangle radii. A star is a plain path, so it
had no widgets with either selection tool.
- geom::corners: the corners of any path (anchors without handles between two
straight sides) and the path with them cut round, inverted round or
chamfered, each corner a circle tangent to both sides, its radius no larger
than takes the cut halfway along its shorter side. Rectangles now cut their
corners with it (bit-identical anchors and layout).
- doc::corners::LiveCorners/set_corners: one model for a live rectangle's,
a live polygon's (new radii/kinds) and any other path's corners (new
LiveShape::Path keeping the uncut outline, plain again once nothing is cut);
radii scale with transforms (Scale Corners) and stay circular.
- object.setLiveShape takes anchor indices for `corners` on any path; polygons
keep a shared radius as their sides change.
- Widgets: Direct Selection on any path, Selection on live rectangles and
polygons; placed on each corner's bisector, the drag follows it, the red
limit outline marks corners at their own limit; the angle preference and
View > Hide Corner Widget apply. Corners dialog and the Properties and
Transform panels' Corner Radius (now on polygons too) work on them.
- Tests for the star, the polygon and a pen path in geom, doc, tools, engine
and ui-egui; docs and ROADMAP.

Live rectangles drew elliptical corners after an uneven scale in v0.4.0;
inconsistent on a rectangle that isn't square:
- doc: LiveShape::fold_scale moves an uneven scale left in `xf` (files
saved before #291) into the size and radii; `transform` uses it, and
`folded()`/`corner_style` give Live Corners document units.
- engine: object.setLiveShape folds that scale first, so setting a radius
or kind (fields, dialog, widgets, MCP) gives circular corners on such
shapes instead of keeping the ellipses.
- geom: max_corner_radius/fitted_corner_radius are the one limit every
corner shares (half the shorter side).
- tools: corner widgets sit at the centres of the corners as drawn (a
radius past the limit put them off the arc, further in along the long
side), drag in document units on stretched shapes, and outline the
edited corners in red at the limit, as the reference app does.
- svg: CSS export writes the drawn radii (CSS would draw a radius past the
limit when its neighbours leave room).
- docs: mcp.md Live Corners, ROADMAP.

Fourteen more Preferences options that were stored but read by nothing now
act, for the mouse and for agents (prefs.set, then pointer_gesture,
press_key or the commands):
- Selection & Anchor Display: Snap to Point and its distance (with Smart
Guides off, View > Snap to Point lands a dragged selection's grabbed
point, drawn points and reference points on anchors and ruler guides);
Move Locked and Hidden Artwork with Artboard (artboard.move, the Artboard
tool and Rearrange; off, hidden art now stays too); Enable Rubber Band for
the Pen and Curvature tools; Handles (solid, hollow, large);
Show handles when multiple anchors are selected (canvas and Direct
Selection's handle picking); Hide Corner Widget for angles greater than.
- General: Transform Pattern Tiles is the default of a new `patterns`
param on object.transform/move/rotate/scale/reflect/shear/transformEach
(journalled when the art uses a pattern), and the transform dialogs get a
Transform Patterns checkbox; Select Same Tint % (off, Select > Same
Fill/Stroke Color takes every tint of a global or spot swatch).
- Type: new type.step {attribute, by} steps size, leading, tracking, kerning
and baseline shift by the Size/Leading, Tracking and Baseline Shift
increments; Increase/Decrease Font Size (Cmd+Shift+. and Cmd+Shift+,);
the Type tool's Alt+arrows (kerning at a caret or tracking, leading,
Shift for baseline shift, Cmd/Ctrl for five steps). Enable Missing Glyph
Protection keeps characters a new font lacks in the font that had them
(text.setStyle, text.setRangeStyle). Fill New Type Objects With
Placeholder Text: type the Type tools place starts with placeholder text,
selected (text.create / text.createInPath take `placeholder`).
Units > General, Stroke and Type were already the single source of truth
(units.rs). Auto Size New Area Type, Show Font Names in English and
Highlight Alternate Glyphs need subsystems the app doesn't have yet and
stay open with the rest of #394.

A live rectangle stored four corner radii but drew them all with the largest,
and the corner widgets always rounded all four corners, so one corner could not
be rounded on its own.
- geom: rectangle_with_corners draws each corner with its own radius and kind
(Round, Inverted Round, Chamfer); a sharp corner is one anchor, a cut one two.
Uniform corners keep the exact rounded-rectangle anchors.
- doc: LiveShape::Rectangle gains `kinds` (saved only when a corner isn't round;
older files read as round), plus helpers mapping anchors to corners.
- engine: object.setLiveShape takes `corners` and `kind`; without `corners` it
edits the Direct-Selected corners, else all four, and keeps the selected
corners selected as their anchors change.
- tools: with Direct Selection, only the selected corners show widgets and a
drag rounds just those; Alt-click cycles the corner kind; double-click opens
the new Corners dialog (also `ui.corners`).
- ui: Properties/Transform radius fields show and set the selected corners;
CSS export keeps per-corner radii and skips cut-in corners.
- docs: mcp.md (Live Corners), control-protocol.md (Corners dialog), ROADMAP.

A live rectangle kept every transform in its `xf`, so a non-uniform scale
(a bounding-box drag, Object > Transform > Scale) stretched the rounded
corners built in untransformed space into elliptical arcs. Scale Corners
off divided the radii by the mean scale, which only compensated uniform
scales.
LiveShape::transform now folds a scale along the rectangle's own sides
(any rotation or reflection, no shear) into w/h and keeps only rotation,
reflection and position in `xf`, so the radii are document lengths and the
path is regenerated with circular corners. Radii scale by the mean scale
(sqrt|det|), which keep_corners undoes for Scale Corners off. Shears and
plain moves keep composing into `xf` as before, so files saved with a
scale in `xf` keep their exact geometry until next scaled or rotated.
A corner-widget drag starts from the radius as drawn (clamped to fit).

The General unit is the active document's units: Preferences > Units >
General sets them (one undo step) and is the units new documents start
in (and the unit shown with no document open); Document Setup changes
only the document. The Transform panel, Properties, the Control bar, the
Info panel, rulers, the status bar, Align spacing, Tabs, paragraph
indents, Pattern Options, dialog distances (Move, shape sizes, path
dialogs, Artboard Options, effect distances, Transform Each, parameter
dialogs), New Document and the canvas measurement labels (smart-guide
sizes, moves, the Measure tool, the Live Corners radius) all follow it,
live. Units > Type drives font size, leading and baseline shift; Units >
Stroke also reaches the Appearance panel and the Magic Wand weight
tolerance. Typed units ("5 mm", "12 pt") work in any field; all ten
units are choices; length preferences show in their unit and accept a
unit; offset/simplify/grid/type-size params read typed units. Typed text
starting with a multi-byte character no longer panics the parser.
