* Fix auto-layout overflow: MeasureFunc, min/max, absolute positioning, text wrap
Layout engine (layout.ts):
- Use Yoga MeasureFunc for text nodes instead of static pre-measurement,
so text wraps correctly when width is determined by flex layout
- Add min/max width/height constraint support (minWidth, maxWidth, etc.)
- Translate counterAxisAlignContent to Yoga setAlignContent for wrap layouts
- Extract configureFlexContainer to share between root and nested frames
JSX renderer (render/renderer.ts):
- Auto-set layoutPositioning ABSOLUTE for elements with x/y inside auto-layout
- Fix text auto-resize: set HEIGHT when text fills parent in auto-layout
Text measurer (renderer/renderer.ts):
- Accept optional maxWidth parameter for constraint-based measurement
* AI prompt: prefer describe over export_image for post-render verification
* Strip TS casts from AI-generated JSX before sucrase parse
AI models sometimes emit `as any`, `as const` etc. in JSX props.
Sucrase with jsx-only transform can't handle these, causing parse errors.
- Strip TypeScript cast expressions before passing to sucrase
- Add forbidden patterns to AI prompt: as any, template literals for
sizes, Math.random()
* Cache text MeasureFunc results to avoid repeated buildParagraph calls
Yoga calls MeasureFunc multiple times per node during calculateLayout.
Each call was creating a full CanvasKit Paragraph — expensive for layouts
with many text nodes. Cache by rounded constraint width.
* AI chat: fix provider settings popover, add max output tokens, fix paste in chat input
- Fix ProviderSettings popover not visible (remove tooltip/popover trigger
conflict, add collision-padding, isolate z-[51])
- Add configurable max output tokens (default 16384) in provider settings
- Pass maxOutputTokens to ToolLoopAgent to prevent truncated tool calls
- Add system prompt size limits: split render calls at ~40 elements
- Fix paste/copy/cut in chat input (stop event propagation to canvas handler)
* Fix 6 layout engine bugs: hidden size, FILL basis, SPACE_EVENLY, alignSelf range, grid stretch, absolute children
Layout engine (layout.ts):
- Guard applyYogaLayout to preserve hidden children dimensions
- Add setFlexBasis(0) for FILL sizing so children share space from zero
- Add SPACE_EVENLY to mapJustify via Justify.SpaceEvenly
- Replace hardcoded STRETCH checks with mapAlignSelf for full range
- Use setWidthStretch/setHeightStretch for grid children instead of flexGrow
- Insert absolute children in Yoga tree via configureAbsoluteChild with
PositionType.Absolute, keeping manual x/y (no write-back)
Types (scene-graph.ts):
- Add SPACE_EVENLY to LayoutAlign union
- New LayoutAlignSelf type: AUTO | MIN | CENTER | MAX | STRETCH | BASELINE
Import (kiwi-convert.ts):
- Map SPACE_EVENLY correctly instead of collapsing to SPACE_BETWEEN
- New mapAlignSelf function for full StackCounterAlign range
Tools (modify.ts):
- Expand set_layout align enum with SPACE_EVENLY
- Expand set_layout_child align_self enum with MIN/CENTER/MAX/BASELINE
Tests: 86 pass (+13 new covering all 6 fixes)
* Grid layout support in JSX renderer, auto-height grids, flex children stretch in cells
Renderer:
- Parse grid/columns/rows/columnGap/rowGap/gap props
- Parse grid child positioning: colStart/col/rowStart/row/colSpan/rowSpan
- Grid prop takes precedence over padding-triggered auto-layout
- SPACE_EVENLY added to ALIGN_MAP
- Numeric columns shorthand (columns={3} → 3×1fr)
- Auto-height: grid without rows sets height=0 for Yoga auto-sizing
- fill sizing in grid children → layoutAlignSelf: STRETCH
- Component builders accept variadic children: Frame(props, ...children)
Layout:
- Grid auto-height: skip setHeight when no gridTemplateRows
- Write back computed height for auto-height grids
- Grid children with layoutMode stretch width to fill cell
- recomputeGridChild: re-run flex layout after grid assigns cell size
(temporarily sets sizing to FIXED so HUG doesn't override grid width)
Export:
- Skip height export for auto-height grids (no rows template)
Tests: 18 new grid render tests covering all paths
* Auto-enable flex for justify/items props, discourage export_image in AI prompt
* Address review: use sucrase typescript transform, don't reset chat on maxOutputTokens change
* Fix lint errors: extract applyFrameSize, wrap nested ternary, remove unnecessary cast
* Remove SPACE_EVENLY — not a valid Figma layout value
* CI: debug LFS pull from R2
* Apply maxOutputTokens dynamically via prepareCall instead of at agent creation
* Fix heavy .fig parse: restore GUID/defID guards, fix optional types
Commit f3eac5a removed null guards from fig-import and
instance-overrides as 'unnecessary conditions', but Kiwi-decoded data
can have NodeChanges without GUIDs and ComponentPropAssignments/Refs
without defIDs. Made the types optional to match reality.
Also fix CI LFS: add git lfs install --force before pull (R2 endpoint
needs the filter registered first).
* Fix Google AI model IDs: gemini-3.1-pro → gemini-3.1-pro-preview
Closes #91
