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).

# Conflicts:
# crates/engine/src/cmd/graph.rs
# crates/svg/src/export.rs
Every edit of an object copied its whole appearance (its fills, strokes and effects, about
540 bytes for a basic object) into the new node, though a move leaves it as it is. Over 45
whole-selection moves of 10,000 paths, undo history grew by 589 MB; now 349 MB (41 % less), and
a nudge or a drag of the selection takes 12 ms instead of 15.
- Node::appearance is a vectorcraft_doc::Shared<Appearance>: copy-on-write. A clone shares it,
and the first change through DerefMut copies it (Arc::make_mut). Reads, writes, equality (also
against a plain Appearance) and the saved form are those of the Appearance itself, so call
sites read and change it as before. Sites that build or assign a whole appearance add .into(),
and the few that need a plain copy take (*n.appearance).clone().
- Node::transform changes the appearance only when it has gradients to transform, and pattern
paints are transformed only when there are some: a move no longer copies an appearance it
doesn't change.
The workspace suite (5,301 tests) and clippy pass with the change; the doc and engine suites
pass again after the transform guard.

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.

The svg crate's new CSS writer (css_rules) gives the CSS web pages style objects
with: rectangles and ellipses as background-color / linear-/radial-gradient(),
border and border-radius; type as font, color, spacing and alignment; shadows,
glows and blur as box-shadow, text-shadow and filter. It shares SVG export's
declarations (transparency, fonts, type spacing, colours, gradient stops), which
moved into svg/src/css.rs. Options: units, absolute position, width and height,
unnamed objects, rasterize unsupported art (as a PNG background-image).
Commands css.selection, css.generate and css.export; UI commands css.copy and
css.exportFile; the CSS Properties panel with a highlighted code view.
