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 Anchor Point tool drags any segment of a selected blend's spine into
a curve, straight ones too, and Direct Selection reshapes a curved spine
segment as it does a path's (a straight one it leaves, as on paths). Both
run the new `object.blend.spine.reshapeSegment`, which bends the segment
with the same math as `path.reshapeSegment`, now shared as
`SubPath::bend_segment`.

A selected blend shows its spine. Direct Selection drags spine points
and handles, the Pen tool adds and deletes points on a selected
blend's spine (object.blend.spine.moveAnchor/addAnchor/removeAnchor).
The straight spine becomes a path on the first edit, its points pinned
to the key objects (append-only BlendSpec.key_anchors): moving a key
moves its end of the spine and the other way round; spines from older
files and Replace Spine still spread the keys evenly. Direct and Group
Selection pick blend keys on the canvas, edits redraw the blend live,
and Release leaves the spine as a path.
