- Unify text measurement by removing duplicate estimators in generation-utils
- Fix optical centering formula to scale proportionally with fontSize
- Round layout positions to whole pixels to prevent sub-pixel artifacts
- Recursively sanitize nested x/y in streaming layout containers
- Fix input trailing icon alignment using fill_container instead of space_between

* feat(canvas): right-align agent badge and add breathing glow border

- Agent badge now right-aligned to frame's right edge instead of after label
- Added breathing glow border around agent-owned frames during generation
- Glow border uses same color and lifecycle as the agent badge
- Removed unused BADGE_GAP constant and useDocumentStore import

* fix(screenshot): update screenshot image for improved clarity and quality

* fix(docs): update WeChat group image path in README.zh.md for consistency

* fix(ai): fix post-generation validation pipeline and text centering

- Fix Agent SDK validation: save temp screenshots inside project dir
  (.openpencil-tmp/) so Claude Code plan mode can read them, instead
  of /tmp/ which is outside the project sandbox
- Enrich validation tree dump with fill colors, stroke, fontSize,
  fontWeight, textAlign, cornerRadius, opacity for comprehensive
  visual analysis
- Add multi-round validation with quality scoring (threshold 8/10),
  500ms stabilization delay between rounds
- Add detailed debug logging to applyValidationFixes showing which
  nodes were found/skipped and property changes
- Fix canvas sync needsTextbox check to also account for textAlign
  (matching isFixedWidthText in factory), preventing IText↔Textbox
  thrashing on every sync tick
- Auto-center text in vertical+center layouts by expanding to full
  container width and injecting textAlign:'center'
- Force Textbox for non-left-aligned text so textAlign is respected
  (IText ignores width and computes its own)

* fix(canvas): use precise text width estimation for fit-content layout

Remove the 14% safety factor from text width estimation when computing
fit-content/natural-width text dimensions. IText auto-computes its own
width and ignores our setting, so the safety margin only inflated the
layout allocation, making text appear left-shifted within its container.

* fix(canvas): center fit-content text in horizontal layouts

For text nodes with fit-content width in horizontal layouts, set
textAlign:'center' to compensate for width estimation inaccuracy.
The estimated box is typically wider than the actual rendered text,
causing left-aligned text to appear visually shifted. Centering
distributes the estimation error evenly on both sides.

* feat(ai): show validation details in checklist panel

- Accumulate validation log (screenshot, analysis, fixes) instead of
  overwriting status messages, so the full process is visible
- Preserve step thinking content in buildFinalStepTags (was discarded)
- Add details field to pipeline items and render in checklist UI
- Each validation step now shows: screenshot captured, issues found,
  quality score, fixes applied

* feat(ai): add visual reference pipeline types and integration hooks

- Add DesignSystem and VisualReference types to ai-types
- Add 'visual-ref' mode to AIDesignRequest and SubTask.htmlReference
- Detect visual-ref candidates in chat handlers (landing pages, websites)
- Wire visual-ref mode in design-generator and orchestrator
- Inject HTML reference snippets into sub-agent prompts

* feat(ai): add modular design principles for sub-agent context

- Add design-principles module with topic files: color, typography,
  spacing, composition, components
- Selectively load relevant principles based on prompt content
- Inject design principles into sub-agent system prompts

* feat(ai): implement visual reference pipeline

- Add design-system-generator: generates color/typography/spacing tokens
- Add design-code-generator: generates HTML/CSS from design system
- Add html-renderer: renders HTML to screenshot via html2canvas
- Add visual-ref-orchestrator: coordinates the full pipeline
  (design system → HTML code → screenshot → enrich subtasks)
- Add html2canvas dependency for client-side HTML rendering

* feat(mcp): default filePath to live canvas and fix cross-platform issues

- Default all MCP tool filePath to live://canvas when omitted, so tools
  operate on the real-time canvas instead of stale files
- Remove filePath from required params in all tool schemas (21 interfaces)
- Fix mcp-server-manager.ts using process.cwd() which fails in Electron
  production on Linux — now checks ELECTRON_RESOURCES_PATH first
- Fix stopMcpHttpServer using SIGTERM on Windows — use taskkill instead
- Force new children reference in applyExternalDocument to ensure canvas
  sync subscriber always detects MCP-pushed document updates

* feat(mcp): enhance design prompt with semantic roles, CJK typography, and layout rules

Add comprehensive design knowledge to MCP design prompt for better
AI-generated designs: design type detection (mobile vs desktop), full
semantic role reference with context-aware defaults, CJK typography
rules, expanded text/layout/form guidelines, and detailed post-processing
documentation.

* feat(ai): implement intent classification for chat handlers

- Replace hardcoded keyword matching with a lightweight LLM call to classify user intent in chat messages.
- Introduce a new function `classifyIntent` to determine if the request is for design generation or conversation.
- Update design request handling in `useChatHandlers` to utilize the new classification method.
- Enhance design prompt documentation to reflect changes in design type detection based on intent rather than keywords.

* fix(ai): handle string qualityScore in validation response parsing

The LLM sometimes returns qualityScore as a string (e.g. "8" instead of 8),
causing it to fall through to 0. Also hide misleading "quality: 0/10" display
when the score couldn't be determined, and log raw response for debugging.

* fix(ai): increase validation timeout to 90s and fix quality score parsing

Agent SDK validation requires spawning a process, reading the image, and
analyzing it — 30s was consistently timing out. Also handle string
qualityScore values from LLM responses and hide misleading 0/10 display.

* fix(ai): fix validation timeout and response parsing

- Increase validation timeout from 30s to 180s (Agent SDK needs time
  for subprocess spawn + OAuth auth + multi-turn image reading)
- Strip <tool_use> XML blocks from Agent SDK response before extracting
  JSON — the tool call XML was confusing the regex, causing qualityScore
  to parse as 0 despite valid JSON being present
- Handle string qualityScore values and hide misleading "quality: 0/10"
- Revert unnecessary direct API key approach for validation

* fix(ai): prevent node ID collisions between generations

When generating new content on a canvas with existing nodes, AI-generated
IDs (e.g. brand-spacer) would collide with previous generations. Now
captures pre-existing node IDs at generation start and checks against
them during upsert sanitization. Remapped IDs are tracked in
generationRemappedIds so progressive streaming updates can still find
their nodes.

* fix(ai): require styleGuide in orchestrator plan and fix validation detail icons

- Add fallback default styleGuide when orchestrator LLM omits it
- Strengthen prompt to mark styleGuide as REQUIRED
- Replace emoji icons in validation details with [done]/[pending]/[error]
  markers for consistent styling with the checklist design system

* feat(server): add port file plugin for server instance discovery

- Introduce a new Nitro plugin that writes a port file on server startup to allow the MCP server to discover the running instance, whether it's a development server or Electron.
- Implement error handling in the Electron main process for writing the port file, logging any failures.
- Update Vite configuration to include additional external dependencies in the rollup configuration.

* feat(electron): implement IPC for retrieving pending file paths

- Added a new IPC handler `file:getPending` to retrieve and clear the pending file path when the React app mounts.
- Updated the Electron API to include `getPendingFile` for renderer access.
- Enhanced the `useElectronMenu` hook to load any pending file on application startup.
- Updated UI components to reflect changes in file handling and improved user experience.

* fix(panels): replace emoji icons with styled icons in validation checklist

- Parse [done]/[pending]/[error] prefixes in detail lines and render as
  styled circle icons matching the parent checklist design system
- Replace remaining emoji markers in design-validation.ts with text prefixes
- Fix isApplied detection to recognize new [done] Applied marker

* refactor(electron): update settings path to use platform-standard app data directory

- Changed the settings file path to utilize Electron's user data directory for better cross-platform compatibility.
- Updated the settings writing function to ensure the user data directory is created if it doesn't exist.
- Added comments to clarify the storage location for different operating systems.
- Implemented a fixed partition for localStorage/cookies to maintain data across server port changes.

* feat(ai): enhance validation with pre-checks, structural fixes, and border detection

- Add design-pre-validation.ts: pure code checks before LLM validation
  - Invisible container detection (same fill as parent → auto-add border)
  - Sibling consistency (majority-rule for height/cornerRadius)
- Add structural fixes to validation: addChild/removeNode operations
  - Icon injection via lookupIconByName with server fallback
  - autoFixParentLayout with child count guard to prevent layout breakage
- Add strokeColor/strokeWidth to safe fix properties for border fixes
- Simplify intent classification: all design requests use visual-ref pipeline
- Fix checklist: "Found N issues" now shows [done] instead of [pending]
- Fix qualityScore: only update when > 0 to preserve valid round scores

* fix(ai): cherry-pick safe validation improvements, drop aggressive pre-checks

Keep: stroke tree dump bug fix (object not array), qualityScore=0 false
positive detection, fit_content→fixed safety guard, empty path removal,
type-specific sibling consistency, repeated fix filtering, screenshot
extraction to design-screenshot.ts.

Drop: detectForcedFixedHeight (destroyed input/button heights),
MAX_VALIDATION_ROUNDS 5 (too many rounds), removal of quality threshold
early stop, section regeneration phase.
