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).

An SVG used as an animation rig lost its hidden alternates and their
rotation pivots: the exporter left hidden objects out (only hidden layers
could be kept), and the importer dropped data-* attributes.
- SVG export: hiddenLayers (on by default for document.save, as before)
now keeps hidden objects too, each written display="none" on its own
element (path, image, text or group). Exports still leave them out
unless asked; the CLI's convert asks, as a conversion keeps the
document.
- An object's own data: ObjectAttributes.data, the data-* attributes in
order (ours, data-name and data-vc-*, aside). The importer keeps them on
the objects and layers they belong to (at most 64 per element), the
exporter writes them back, the native format saves them (missing in
older files), and object.setProps {data: {key: value|null}} sets or
removes them.

Window > Attributes (Cmd+F11) shows Overprint Fill/Stroke, Show/Don't Show
Center, Reverse Path Direction Off/On, the non-zero / even-odd fill rule,
Image Map, a URL field with recent URLs and a Browser button, and a note.
New commands attributes.set and path.setFillRule; path.reverse takes ids and
reversed; attributes.info reports every value. Objects keep the attributes in
Node.attrs. SVG export wraps linked objects in <a>, and import reads links
back. The canvas draws the centre point of selected objects that show it.
