Move engine (scene-graph, renderer, layout, codec, kiwi) into
packages/core/ as a Bun workspace package. The app's src/engine/
files become thin re-export shims so all existing imports still work.
- Bun workspace with packages/core
- Zero DOM dependencies in core
- Headless-friendly CanvasKit init (locateFile option)
- Constants split: engine constants in core, UI constants in app
- All 76 unit tests pass, lint + typecheck clean, vite build works
- Move Vector, Matrix, Rect to src/types.ts as shared primitives
- GradientTransform is now a type alias for Matrix
- Consolidate Window API declarations (File System Access,
queryLocalFonts) in src/global.d.ts
- Remove duplicate KiwiNodeChange from fig-export.ts and
clipboard.ts, reuse NodeChange from kiwi/codec.ts
- Add missing fields to codec NodeChange: frameMaskDisabled,
stackWrap, stackPositioning, stackChildPrimaryGrow, vectorData
- Widen codec Paint.type and Effect.type unions to match scene-graph
- Replace inline Rect definitions across 5 files with shared type
- fig-export.ts fillPaints now constructs typed Paint objects
- Fork kiwi-schema from source TypeScript (evanw/kiwi), drop npm dep + patch
- Deduplicate GUID/Color types into src/types.ts
- Extract UI colors and default fills into src/constants.ts
- Replace hand-rolled hex parsing with culori library
- Extract demo shapes from App.vue into src/demo.ts
- useUrlSearchParams from VueUse for test mode detection
- Move fig-file/fig-import into kiwi/ (format layer)
- Delete PoC files (poc-yoga.ts, poc-test.ts)
