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).

document.export {format: "psd"} writes layered bitmaps (8 bits per channel),
written from the format's public specification: RGB, CMYK (ink amounts) or
grayscale, the resolution and an embedded profile, PackBits channels, and the
merged image (the flat render). layers (default true) draws each top-level
layer alone as a pixel layer, cropped to what it paints, with its name,
opacity and blend mode; a background colour becomes a Background layer.
maxEditability turns layers and sublayers into groups and every object into a
layer named as the Layers panel names it (text by its text); clipping, masked,
knockout or appearance-carrying layers stay one layer. hiddenLayers writes
hidden layers hidden instead of leaving them out; layers: false writes a flat
image on white. At most 30000 pixels a side.
Export As offers PSD with the psdOptions dialog (the PNG Options rows, then
Color Model, Flat Image / Write Layers with Maximum Editability and Include
Hidden Layers, Embed ICC Profile). Tests read the files back with the psd
crate (MIT OR Apache-2.0, a dev-dependency).
