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).

Type and symbol instances attached to a plane keep their art and carry a projection
(Node.perspective.projection, append-only); the canvas and every export draw their outlines
through it (reshape/bake), so they are foreshortened and stay type and symbol instances. Bounds,
hit testing and transforms follow the projection. Object › Perspective › Edit Text
(perspective.editText, or double-clicking with the Perspective Selection tool) shows the type flat
where it is drawn in isolation mode; exiting isolation projects it again. Release with
Perspective keeps their look. Copies, pastes, duplicates and Selection-tool moves keep the
attachment (the art moves as dragged). Flare, spiral and polar grid draw on the active plane, and
so do the click-to-size shape dialogs (perspective.draw `at`: sizes in plane units).

The Perspective Selection tool shows the selection's bounding box in perspective; its handles
scale in plane space (perspective.transform; Shift proportional, Alt from the centre). Alt-drag
moves copies that stay attached, pressing 5 while dragging moves along the plane's normal
(ToolKey::Digit, delivered by the canvas and MCP press_key), and the arrow keys nudge in
perspective (perspective.nudge). Transform Again repeats the last perspective move or scale in
plane space. Attachments (plane and depth) now live on the objects (Node.perspective), so copies,
duplicates and pastes keep them; grids from older files hand theirs over. Homography moves to
vectorcraft-geom. Hint-bar text for the tool.
