Variable/collection IDs (e.g. 'VariableCollectionID:42:1') parsed via
stringToGuid produced NaN sessionID, which Kiwi encodes as 0 — same
GUID as the DOCUMENT node. This overwrote DOCUMENT in changeMap during
re-import, causing all pages to be lost.
Fix: generate unique GUIDs for collections, variables, and modes via
localIdCounter instead of parsing string IDs. Pass varIdToGuid map
through to serializeVariableBindings for consistent references.
Test has never passed since it was added (3b32b4d). Add console.log
to show page counts, node counts, and internal-only flags so the CI
log reveals what the export→parse roundtrip actually produces.
* Perf: cache label collection, offload .fig compression to worker
Label cache: collect sections/components once per scene change,
filter by viewport on each frame. Eliminates full tree walk during
pan/zoom (~17ms/frame → <1ms on large files).
Export worker: move fflate compression off the main thread to prevent
frame drops during save (451ms+ → non-blocking).
* Perf: worker-based .fig parsing, instance index, non-blocking font loading
- Offload .fig parsing (unzip + Kiwi decode) to a Web Worker
- Add instance index (componentId → Set<nodeId>) for O(1) getInstances()
- Defer graph event subscription during file open to skip redundant syncs
- Make font loading non-blocking — render immediately, load fonts in background
- Copy image buffers before worker transfer to prevent detached ArrayBuffer crash
- Show toast on font load failure and file open errors
- Cache failed Google Fonts families to avoid repeated network requests
- Fix missing ref import in FillPicker
- Yield to UI between parse and layout for responsive loading spinner
