- Screens: frames can be declared screens or overlays (set_screens, inspector toggles,
"Declare N screens"). Agent edits to layers hidden behind a drawer/modal in a screen
are refused unless allowHidden; partly covered ones are reported. get_basic_info lists
screens, get_node_info reports visibility, lint skips hidden layers, On click lists
screens, nested screens get canvas labels. Spec in specs/screens.
- Pages and versions are stored as zstd-compressed compact JSON (.json.zst, format v3);
legacy .json still reads and is replaced on save.
- Editor keeps a per-layer change log; the scene cache re-tessellates only changed layers
and no longer keeps a copy of every node (less RAM).
- Canvas perf: zoom settle and LOD, 24-byte vertices, vsync-paced redraws, idle hover
skip, malloc relief when idle, off-screen frame labels skipped, layer-panel heights
memoized across frames, run recount on a background thread.
- Frame labels: no label on tiny frames, overlapping labels dropped, ellipsis.
- Selects: menu sizes to content (capped), path labels keep the name, scroll, tooltips.
- Settings: performance monitor page, agent logos, chat page scroll fix.
