The Selection tool shows two pie widgets just outside a selected live
ellipse while the bounding box shows: one at the Pie Start Angle and
one at the Pie End Angle. Dragging one sets its angle to the angle of
the outline's point that lies in the direction of the pointer from the
ellipse's center, in one undo step, through `object.setLiveShape`'s
`pieStart` or `pieEnd`. Double-clicking one makes the ellipse whole
again (0° to 360°). Where the two widgets coincide, as on a whole
ellipse, a press takes the End widget.

Rarely set fields move into one optional boxed NodeExtras, and large NodeKind payloads (images,
live shapes, blends, envelopes) are boxed. Every object, and every undo step that copies it,
shrinks: a 50k-path move keeps ~24.5 MB per step instead of ~40 MB. Files stay byte-identical
(Node keeps its flat JSON through a borrowed Serialize and a from-wire Deserialize, no flatten),
and loading is slightly faster. Undo and redo reuse their step's size estimate instead of
walking the document again (8.3 -> 5.6 ms for a 50k-path move).

The corner widgets only showed when the selection was exactly one path.
Now every selected path that has them shows its widgets: live rectangles
and polygons with the Selection tool, any path with Direct Selection,
each with its own corners (all of a path selected whole, the
Direct-Selected ones otherwise). Dragging any widget rounds every shown
corner of every path in one step, Alt-click cycles their kind, and the
red limit outline covers them all; a double-click opens Corners for the
path it was on. Each widget is drawn in its own layer's colour.
object.setLiveShape takes items: [{id, corners?}], several objects each
with its own corners, which the drag sends.

A selected live polygon now shows Illustrator's Polygon Properties in the
Transform panel and the Properties panel's Transform section: side count,
angle, corner type and radius, radius, side length and Make Sides Equal
(enabled once an uneven scale has made its sides differ). Before, only the
side count and corner radius were there.
object.setLiveShape takes polygonAngle (degrees counterclockwise),
polygonRadius and sideLength (points, centre to vertex / side) and
makeSidesEqual, which drops the uneven scale and shear and keeps the
polygon's centre, angle and mean radius. Each call is one undo step; a
radius or length that isn't a number above 0 is an error. A star stays a
plain path, as in Illustrator.

An ellipse kept pie angles in its model, but nothing drew or set them. Now
the Transform and Properties panels show Ellipse Properties with Pie Start
Angle, Pie End Angle and Invert Pie, as in Illustrator, and
object.setLiveShape takes {pieStart, pieEnd, invertPie}. The pie runs
counterclockwise on screen from the start angle (0 at 3 o'clock) to the
end angle and closes through the centre; 0 to 360 is the whole ellipse,
an end of 0 means 360, and Invert Pie swaps the angles to show the other
part. One undo step each; a bad angle is an error. The labels are
translated in every complete language. The on-canvas pie widget is still
to come.

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.

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.
