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).

Text geometry, clips, clip paints, effect art, brushes, live effects, pattern tiles and freeform
grids were capped by entry count and cleared wholesale on overflow, so a document past the cap
(e.g. more than 4,096 type objects) recomputed every entry on every frame. A FrameCache keeps
per-entry byte sizes and last-used frames, drops the least recently used entries of earlier
frames, and sweeps stale ones. Text geometry keeps its glyph outlines once instead of twice.

Decoded images were kept per Renderer at full resolution and never evicted, so the canvas,
render worker, thumbnails and panels each held their own copy (96 MB per 24 MP photo).
They now live once in a process-wide LRU store keyed by content, with optional mip levels
(RenderOptions::image_mips, off by default so exports stay identical). Thumbnail renders
now sweep their caches, and shadow/effect rasters share a 512 MiB budget and match by Arc.
