Extracted shared helpers to eliminate copy-pasted code:
Core:
- computeAbsoluteBounds() in geometry.ts — replaces 4 bounding box loops
- makeDocumentNodeChange/makeCanvasNodeChange in kiwi-serialize.ts
- parseFigBuffer/parseFigKiwiContainer in kiwi/fig-parse-core.ts
(fig-parse-worker.ts: 103 → 11 lines)
- createDefaultEditorState() — shared between core + app store
- calcClusterConfidence() in tools/analyze.ts
- retryWithNormalizedFamily() in fonts.ts
- getVectorNode() in tools/vector.ts
- renderFills() helper in renderer/scene.ts
- withNodeBounds() helper in renderer/overlays.ts
- drawNodeHighlightRect() in renderer/highlight-rect.ts
- isInViewport() in renderer/label-cache.ts
App:
- decodeTauriStderr() in utils/tauri.ts
- printNodeResults() in cli format.ts
Remaining 28 clones are: text-editor cursor movement (inherent),
xpath DOM traversal (inherent), small 5-line patterns too
context-specific to extract.
