Reduce cyclomatic complexity below 20 in all core functions
Refactor 24 complex functions across 14 files by extracting
dispatch branches and property-group handlers into focused helpers.
kiwi/kiwi-convert.ts (4 functions, was 22-81):
- nodeChangeToProps → 6 property-group converters
- convertOverrideToProps → 5 override applicators
- importStyleRuns → 3 style-run helpers
- mapNodeType → NODE_TYPE_MAP lookup table
kiwi/instance-overrides.ts (3 functions, was 28-44):
- applyDerivedSymbolData → resolveDsd* helpers
- applyComponentProperties → assignment/override applicators
- propagateOverridesTransitively → clone/sync helpers
kiwi/fig-import.ts (2 functions, was 34-40):
- importNodeChanges → buildChangeMaps, importPages, etc.
- importVariables → importCollections, resolveVariableType, etc.
render/export-jsx.ts (2 functions, was 70-85):
- collectProps → property-category extractors
- collectTailwindClasses → Tailwind class-group extractors
render/renderer.ts: propsToOverrides (78) → style-category helpers
renderer/scene.ts: renderNode (46), renderShapeUncached (30) →
phase extractors (transforms, content, children, strokes)
renderer/renderer.ts: buildParagraph (34) → buildTruncateOpts,
addStyledRuns
svg-export.ts: split into svg-export.ts + svg-export-defs.ts +
svg-export-paths.ts; renderNode/renderTextNode/nodeShapeElements
all reduced via helper extraction
kiwi-serialize.ts: sceneNodeToKiwi (44) → 6 property serializers
clipboard.ts: importClipboardNodes (36) → 5 focused helpers
scene-graph.ts: hitTestChildren (31) → containsPoint,
hitTestOpaqueContainer, hitTestTransparentContainer
tools/analyze.ts: serializeNodeProps (23) → 4 prop serializers
