- Configure oxfmt custom import groups for workspace, app, package, and test aliases
- Keep type imports grouped with their matching source category instead of one global tail group
- Expand the format script to cover formatter config, Vite files, and scripts
estimateTextSize() now tries opentype.js per-glyph advance widths
before falling back to the rough 0.6 × fontSize × charCount heuristic.
Since font data is already cached via loadFont(), this gives accurate
variable-width measurement for any loaded font — no CanvasKit needed.
Parsed opentype.js Font objects are cached per family+style to avoid
reparsing on every layout pass.
The estimateTextSize() fallback (fontSize × 0.6 × charCount) produced
wildly inaccurate results, causing 26K node mismatches on material3.fig.
Nodes imported from .fig files already carry Figma's computed dimensions —
use those instead. Falls back to the estimate only for newly-created
nodes with the 100×100 default size.
Reduces headless layout mismatches by ~56% (26,299 → ~11,669), with
TEXT node mismatches dropping 92%.

* Fix text rendering: always use paragraph wrapping, font fallback, batch tools, severity levels
Rendering:
- renderText: always use paragraph when fontProvider available, not just
when node-specific font loaded — fixes single-line overflow for Georgia/
non-Inter fonts
- buildParagraph: add Inter as fallback fontFamily so paragraph wraps text
even when requested font not yet loaded
- measureTextNode/buildTextPicture: remove isNodeFontLoaded gate — measure
with fallback font for consistent layout↔rendering
- TEXT_PICTURE_KEYS: add width/height so textPicture invalidates on resize
- renderText drawText fallback: clip to node bounds
- onAfterExecute: invalidate textPictures after font load
Layout:
- estimateTextSize: accept maxWidth, compute multi-line height
- toJSON: depth parameter with childCount fallback
AI tools:
- batch_update tool: multiple set_layout/set_layout_child in one call
- describe: accept ids array for multi-node inspection
- Issue severity (error/warning/info) with pattern classification
- checkNestedFlexWithoutFill: cross-axis fill tolerance
- CORE_TOOLS trimmed 34→27, rest moved to EXTENDED
- System prompt: batch_update, describe ids, severity rules, font/text
wrapping guidance, card grid patterns
* Add Pexels stock photo integration for AI chat
- stock_photo tool: search Pexels by query, download image, apply as
IMAGE fill on any node. Picks resolution based on node dimensions.
- Pexels API key stored in localStorage, synced to core via
setPexelsApiKey on change
- ProviderSettings UI: Pexels API key input with link to get free key
- System prompt: stock photo usage guidance
- Added to CORE_TOOLS so AI can use it in every session
* Batch stock_photo + calc, 4-phase workflow, fix wrap false positives
- stock_photo: accepts JSON array of requests, all fetched in parallel.
Rejects nodes with children (leaf shapes only). One call replaces 14.
- calc: accepts JSON array of expressions or single string. One call
replaces 3 separate calc invocations.
- System prompt: 4-phase workflow (plan → skeleton → content → polish).
Batch stock_photo and calc examples. Updated step budget.
- describe-layout-issues: skip 'nested flex may collapse' for wrap
containers (pill/tag frames are intentionally HUG). Extract
childNeedsFill helper to reduce complexity.
* Fix nested flex false positive for pills, single-root render rule
- describe-layout-issues: skip 'nested flex may collapse' when a sibling
already has grow or fill — pill/badge frames next to flex-grow content
are intentionally small (e.g. BreakingLabel next to ticker text)
- System prompt: render must have exactly one root element. Stock_photo
401 fallback: tell user, don't eval gradients.
* Rework workflow: render complete sections, not empty frames
Phase 2 now prescribes 5-7 renders, each producing a complete section
(nav, hero, stories, opinions, sidebar, footer) with placeholder images,
real text, proper auto-layout. No more empty frames to fill later.
Removes the fill content phase — skeleton IS the content, just without
real photos. Phase 3 is now just polish (batch stock_photo + fixes).
Step budget: 12-15 steps instead of 15-30.
* Pexels key input: match AI key behavior
Same pattern as the AI provider key — intermediate ref, 'Key saved —
enter new to replace' placeholder, Clear button, save on change. No
longer exposes the raw key in the input field.
* No empty frames in skeleton, select nodes after each tool
- System prompt: explicit rules against empty frames, no pre-creating
wrapper frames for future content. Each render = complete section with
visible placeholders. Render 1 = only nav+ticker, not the whole page
with empty containers.
- tools.ts: set selection to flash node IDs after each mutating tool,
so user sees which section AI is working on (selection border persists
vs flash which is transient).
* AI overlay: pulsing blue while working, green flash on done; skeleton workflow
Rendering:
- ai-overlays.ts: new module with pulsing blue border (sinusoidal
opacity 0.3-0.8 at 1.5s period) for nodes AI is working on, green
fade-out flash (800ms) when done
- renderer.ts: aiMarkActive/aiMarkDone/aiClearAll methods, drawn after
regular flashes
- constants.ts: AI_ACTIVE_COLOR, AI_DONE_COLOR, timing constants
Integration:
- ai-adapter.ts: onBeforeExecute now receives args (for target ID)
- tools.ts: marks target node (id or parent_id) active before tool
executes, marks done via onFlashNodes after completion
- editor.ts: aiMarkActive/aiMarkDone/aiClearAll forwarded to renderer
Workflow:
- System prompt: 3-phase skeleton workflow. Phase 2 renders gray
placeholder blocks (Rectangle bg=#E2E8F0) for every section — page
looks like wireframe before any real content. Phase 3 replaces
skeletons with real content. Phase 4 batch stock_photo + polish.
* render replace_id: atomic skeleton-to-content swap, fix AI overlay lifecycle
render tool:
- New replace_id parameter — renders new content, places it at the
skeleton's position in parent, then deletes the skeleton. No visual
gap between skeleton removal and content appearance.
AI overlay fixes:
- Track lastActiveIds across before/after execute — aiMarkDone clears
the exact nodes that were marked active, not just the result IDs
- aiFlashDone: direct green flash on result nodes (not gated by
_aiActiveNodes membership)
- replace_id included in target ID detection for active marking
System prompt:
- Phase 3 uses render({ replace_id }) instead of delete_node + render
* Fix gradient fills, nested flex false positives, render insert_index, h=hug prompt
- set_fill: gradient support with color_end + direction (top-bottom,
left-right, etc). Uses proper Matrix type. No more eval for gradients.
- describe-layout-issues: skip nested flex warning for all non-MIN
alignments (SPACE_BETWEEN, CENTER, MAX) — not just SPACE_BETWEEN
- render: insert_index parameter for controlling child order
- system prompt: page frame h="hug" not fixed height
- AI overlay: mark active on any tool with target ID (not just
mutating), clear previous active in onBeforeExecute
* Add desktop business news site example to system prompt
Full workflow example: skeleton with gray placeholders → replace_id
content fills → batch stock_photo. Shows 12-col grid pattern, card
components, section headers, sidebar widgets, h=hug page frame.
Complements the existing mobile app UI example.
* Drop blue active pulse, keep only green done flash
Blue active marking was invisible — tool execution is 20-80ms (one
frame), AI thinking happens between tool calls where no hooks fire.
Green done flash on result nodes works and is visible.
* Blue pulse on skeleton during AI tool streaming
Watch streaming message parts in ChatPanel — when a tool part appears
with state 'call'/'partial-call' and has replace_id or parent_id in
args, mark that node active (blue pulse). When tool transitions to
'output-available', mark done (green flash). This shows the pulsing
blue border on the skeleton wireframe frame while AI generates JSX,
and switches to green when the content replaces it.
* AI overlay debug log section, watch tool parts by toolCallId
- chat-debug.ts: aiOverlayLog array + AI OVERLAY LOG section in debug
output showing every part/mark-active/mark-done event with timestamps
- ChatPanel.vue: check parts by toolCallId instead of isToolUIPart,
log all overlay events to aiOverlayLog for debugging
* Fix AI overlay: use 'input' not 'args' for tool part params
Vercel AI SDK UIToolInvocation uses 'input' field (not 'args') for
tool call parameters. The watch was checking p.args which was always
undefined, so no overlay events ever fired. Also use p.type instead
of p.toolName for the log.
* Move AI overlay to onBeforeExecute/onFlashNodes, reorder render params
- onBeforeExecute: mark replace_id/parent_id active (blue pulse)
- onFlashNodes: clear active, flash done on new nodes (green)
- Reorder render tool params: replace_id first so streaming partial
input reveals target ID before JSX body
- Remove ChatPanel watch — all overlay logic in tools.ts now
- Add aiClearActive() to renderer (clears active without touching
done flashes)
* Wait 2 rAF frames after marking active before tool execute
onBeforeExecute marks the target node active (blue pulse), but
execute ran immediately after without yielding to the render loop.
The blue frame was never painted because markActive → execute →
clearActive all happened in the same JS task. Now await two
requestAnimationFrame callbacks so the canvas renders at least one
blue-pulse frame before execution starts.
* Add comprehensive AI overlay debug logging to chat debug log
Both streaming watch (ChatPanel) and tool execution hooks (tools.ts)
now log every event to aiOverlayLog with full state: renderer exists,
activeNodes count, hasFlashes, node existence. This will show exactly
what happens and why the blue pulse is or isn't visible.
* Filter partial node IDs in streaming overlay watch
During input-streaming, replace_id may be partially received (e.g.
'0:' without the number part). Guard with isValidNodeId check.
Also refactor watch callback into collectPendingTargets +
syncOverlayState to stay under complexity limit.
Analysis of last debug log:
- Hero: only 235ms active (streaming didn't deliver replace_id early)
- Stories: 14.8s active — should be clearly visible
- Opinions: 12.5s, LatestNews: 11.5s, Stocks: 9.8s — all long enough
- Hero was the only one too fast to notice
* Fix undo race, JSX pragma conflict, partial ID overlay, add deletion log
- Fix undo snapshot race condition: replace shared `let beforeSnapshot`
with a per-tool stack. Vercel AI SDK runs tool calls from one step via
Promise.all — concurrent mutating tools overwrote the shared snapshot,
causing wrong undo entries and potential content loss.
- Fix 'h is not a function' JSX error: rename sucrase pragma from `h`
to `__h`. When AI writes `.map((h, i) => ...)`, the loop variable
shadowed the pragma, crashing render.
- Fix partial node ID `0:1` in overlay: strengthen `isValidNodeId` to
require both parts ≥2 chars and verify node exists in graph. During
streaming, `replace_id: "0:1811"` arrives as `0:1` → `0:18` → etc.
- Add deletion log to SceneGraph: `_deletionLog` records id, name,
type, parentId, timestamp, and truncated stack for last 200 deletions.
Included in debug log as NODE DELETION LOG section to diagnose the
intermittent frame disappearance bug.
* Reduce find_nodes spam and describe bloat in system prompt
- Instruct AI to reuse IDs from render results and describe output
instead of calling find_nodes to rediscover them (saves 8+ calls)
- Recommend depth=1 for full-page describe, depth=2 only for sections
* Auto-depth describe + validate-after-render workflow
Describe tool now auto-picks depth based on subtree size when depth
is omitted: ≤15 nodes → depth 4, ≤40 → 3, ≤100 → 2, larger → 1.
Max raised to 5 for explicit overrides.
Prompt updated: after each render replace_id, call describe on that
block (auto depth gives full detail on small sections). Every 2-3
content renders, describe root at depth=1 to catch cross-section
layout issues early.
* Enforce describe-after-every-render in system prompt
Show explicit render → describe → fix pattern with code example.
AI was skipping per-block validation and batching all describes
at the end, causing compounding layout errors.
* Add describe rules: nested text, missing padding, button padding, row centering
Four new layout issue detectors in describe-issues.ts:
- Nested Text (error): Text node inside Text causes overflow.
Suggestion: split into separate Text elements in flex row.
- Zero padding container (warning): Frame with fill + text children
but no padding — content touches edges.
- Button without padding (warning): Button-like frame with children
but zero horizontal padding.
- Row without vertical centering (warning): Horizontal flex with
items=start, tall container, and short children — suggests
items=center.
All verified with bun -e tests including false positive checks.
* Fix gradient alpha loss, add undersize child detection
Gradient fix: set_fill with color_end was overwriting alpha to 1
on both gradient stops (`{ ...c, a: 1 }`). Now preserves original
alpha from parsed hex — #00000000 → a:0, #000000AA → a:0.667.
This caused transparent-to-dark overlays to render as solid black.
New describe rule: detect child significantly narrower than parent
in a container without auto-layout (e.g. 100px Rectangle inside
896px Frame). Suggests adding flex + w=fill. Caught the HeroImg
bug that describe previously missed.
* Auto-include issues in render result, no separate describe needed
Render tool now scans the created subtree for errors/warnings and
includes them in the response. AI gets issues automatically without
needing to call describe — eliminates the pattern where AI skips
describe on 'simple' sidebar blocks.
Example response:
{ id: '0:42', name: 'Card', issues: [
{ node: 'Text', id: '0:45', message: 'no color', severity: 'error' }
] }
* Run layout before collecting render issues
Issues were checked on raw node sizes (default 100px) before
computeAllLayouts ran in onAfterExecute. Now render calls
computeAllLayouts inline before collectSubtreeIssues, so issues
reflect actual computed dimensions.
This fixes hundreds of false 'X 100px overflows parent' warnings
that made AI chase nonexistent problems.
* Revert auto-issues in render and layout-before-issues
Reverts 09a9b89 and 70c116a. Auto-including issues in render
result caused false positives (100px default sizes before layout)
and made AI chase nonexistent problems, degrading output quality.
* Clean up AI chat PR: remove debug scaffolding, add stock photo provider adapter
- Delete _deletionLog (stack traces on every node deletion)
- Delete aiOverlayLog and all debug push() calls
- Delete succesful_prompt_diffucult_ux.md (raw debug dump) and tokens.md (empty)
- Remove double-rAF hack from ai-adapter (added 32ms to every tool call)
- Restore simple beforeSnapshot for undo (was matching by tool name)
- Remove 70-line overlay state tracker from ChatPanel.vue
- Remove Math.* regex hack from calc (expr-eval has builtins)
- Refactor stock-photo into provider adapter: Pexels + Unsplash
- Add Unsplash key management to settings UI and use-chat composable

Engine:
- layoutSizingVertical/Horizontal setters now use child's own layout
direction (not parent's) to map primary/counter axis — matches Yoga
- FILL on cross-axis uses alignSelf:Stretch instead of flexGrow
(flexGrow only works on main axis, caused even distribution bug)
- FILL on main axis auto-sets layoutGrow=1 for leaf nodes
This fixes the 20-step debugging spiral where AI set FIXED heights
on HORIZONTAL children inside VERTICAL parent but Yoga ignored them
(wrote primaryAxisSizing via parent axis, Yoga read counterAxisSizing
via child axis — never saw the FIXED value).
Describe noise reduction:
- Suppress 'absolutely positioned inside flex' — intentional for
decorative overlays (selection handles, badges)
- Suppress 'justify=between with HUG' when node fills parent width
- Suppress 'fixed size + grow' when sizing is FILL (standard pattern)
- 'Inconsistent padding' requires 3+ siblings (not 2)
Prompt:
- Bail-out: delete and re-render after 2 failed set_* attempts
- eval restricted to operations, not layout debugging
layout.ts: When text fills width (stretch in col parent), MeasureFunc
now uses Yoga's constraint width directly instead of clamping to
the 100px default fixedWidth.
prompt: Emphasize that ALL intermediate flex containers need w="fill",
not just the first level. grow inside HUG = zero width.
configureTextLeaf for HEIGHT mode was calling yogaChild.setWidth(child.width)
unconditionally, which locked text at the 100px default. This blocked
Yoga's alignSelf:stretch from expanding text to the parent's cross axis.
Now skips setWidth when text has layoutAlignSelf=STRETCH in a vertical
parent (w="fill" case). Same fix for the headless fallback path.
Test: text with w="fill" in flex="col" stretches to 260px (300 - 2×20 pad).
Two fixes:
1. layout.ts: Add estimateTextSize() fallback (~0.6 × fontSize per char)
for when MeasureFunc returns null (font not loaded) or CanvasKit is
unavailable. Previously fell back to child.width/child.height which
defaults to 100×100 for new nodes, blowing up every HUG container.
2. ai/tools.ts: Only call computeAllLayouts + requestRender + push undo
for mutating tools (def.mutates). Read-only tools (describe, get_jsx,
node_bounds, etc.) were triggering full layout recompute on every call,
wasting cycles and potentially destabilizing layouts during AI sessions.
- Replace non-null assertions with guards/optional chaining
- Replace useless spreads with Array.from() where mutation-safe
- Remove unused imports, variables, and functions
- Fix no-base-to-string with proper type narrowing
- Fix sort without comparator, new Array() pattern
- Prefix unused parameter with underscore
Warnings: 76 → 42 (remaining are max-lines, justified any casts, vendored code)
Text nodes with textAutoResize=WIDTH_AND_HEIGHT kept their 100×100
default SceneNode size when MeasureFunc was unavailable (no CanvasKit),
blowing up every HUG container.
Add fallback estimator (~0.6 × fontSize per char) in layout.ts so
headless layout produces sane sizes.
DO NOT change textAutoResize defaults in renderer.ts without testing
headless layout — see comments there and in layout.ts.
* 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

* Switch to @open-pencil/yoga-layout with CSS Grid support
Use our fork (open-pencil/yoga, grid branch) which cherry-picks the
upstream CSS Grid PRs (#1893–#1898) onto current main. The JS bindings
are ported from the old embind approach to the new wasm_bridge.c API.
npm:@open-pencil/yoga-layout alias keeps all imports as 'yoga-layout'.
Also handle FinalizationRegistry change (upstream #1908) — node.free()
no longer exists, nodes are garbage collected automatically.
* Add CSS Grid layout mode
Scene graph:
- LayoutMode gains 'GRID' option alongside HORIZONTAL/VERTICAL
- GridTrack type (sizing: FIXED/FR/AUTO, value) for track definitions
- GridPosition type (column, row, columnSpan, rowSpan) for children
- New node props: gridTemplateColumns/Rows, gridColumnGap, gridRowGap,
gridPosition
Layout engine:
- buildGridTree() sets Display.Grid and maps GridTrack[] to Yoga's
setGridTemplateColumns/Rows API with FR/Points/Auto track types
- Grid children use gridPosition for column/row placement with span
- Flex layout path unchanged
Store:
- setLayoutMode('GRID') auto-creates NxM track grid based on child
count (sqrt heuristic), defaults to 1fr tracks
UI (LayoutSection.vue):
- Grid button (grid-2x2 icon) added to flow direction row
- Columns/Rows track editors: ScrubInput for value + AppSelect for
sizing mode (Fill fr / Fixed px / Auto), add/remove buttons
- Separate column gap and row gap ScrubInputs
- Wrap button hidden when grid is active
- Flex alignment grid hidden when grid is active
Kiwi serialization skips GRID mode for now (no .fig codec support).
* Add grid layout integration tests
12 new test scenarios covering:
- Basic 2x2 grid, fixed columns, mixed fr/fixed, unequal fr weights
- Column gap, row gap, both gaps combined
- Padding offsets
- Explicit gridPosition placement, column span, row span
- Absolute children skipped
- Hidden children collapsed
- Nested grid inside flex parent (computeAllLayouts)
Also fix: grid frames as children of flex parents now correctly use
Display.Grid via configureChildAsGrid() instead of falling through
to configureChildAsAutoLayout() which set FlexDirection.
* Deduplicate grid yoga configuration
Extract configureAsGrid() and createGridChildNode() shared by
buildGridTree (root-level grid) and configureChildAsGrid (grid
nested inside flex parent).
* Add grid layout to changelog
* Add grid support to JSX and Tailwind CSS export
OpenPencil format: grid → columns/rows/columnGap/rowGap props,
child colStart/rowStart/colSpan/rowSpan.
Tailwind format: grid grid-cols-N grid-rows-N gap-x-* gap-y-*,
mixed tracks use arbitrary values (grid-cols-[200px_1fr_auto]),
child col-start-*/row-start-*/col-span-*/row-span-*.
Both formats: padding emitted for grid frames (shared with flex),
flex-only props (justify/items/wrap/gap) scoped to isFlex.
* Remove duplicate gridTrackToTw, use shared formatTrack
Also drop unused GridTrackSizing import from LayoutSection.vue.
* Fix grid icon: use layout-grid instead of grid-2x2
unplugin-icons can't resolve icon names with digits after hyphens
(grid-2x2 → grid2x2 which doesn't exist).
* Polish layout UI and fix auto-layout behavior
- Replace text labels with compact icons: ↔/↕ for gap, ☐ for uniform padding, T/R/B/L for per-side padding
- Direction-aware gap icon: ↕ for vertical, ↔ for horizontal
- Pin +/− padding toggle button right of gap input
- Fix alignment grid axes for vertical layout (transpose primary/counter)
- Fix grid switch: set FIXED sizing, compute frame size from children
- Remove hardcoded white fill from Shift+A wrap
- Auto-detect horizontal vs vertical from selection bounds
* Add flex-to-grid switch integration test
Verify HUG frame expands and children are placed in 2x2 grid
when switching from vertical flex to grid layout.
* Update changelog for grid layout
- Resolve symbolOverride guidPaths by overrideKey instead of guid
- Handle overriddenSymbolID for instance component swaps
- Propagate overrides transitively through the componentId clone chain
- Preserve internalOnly flag on canvas nodes during export
- Scope computeAllLayouts to current page for paste/undo/font-load
Instance population can create scene graph children that don't
have corresponding Yoga nodes (e.g. when the Yoga tree was built
before cloned children were fully resolved). Skip null yogaChild
instead of crashing.
During .fig import, instance nodes have no children — Figma expects
them to be cloned from their component. The componentId references
used original Figma GUIDs that didn't match our generated node IDs.
Fix:
- Track original GUID → new node ID mapping during import
- Remap all instance componentId references after node creation
- Iteratively populate empty instances from their components
(multiple passes needed since cloning creates new instances)
Text nodes with textAutoResize=WIDTH_AND_HEIGHT now use an estimated
content width instead of the node's current width when computing
auto-layout. Fixes month headers (and similar centered text in
auto-layout) appearing left-aligned after paste.
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
