- Updated Mermaid dependency to latest v11.11.0
- Migrated all rendering code to use Mermaid v11 async API
  - Changed from deprecated init() to run() method
  - Added async parse() validation before rendering
  - Updated HTML export to use new API
- Added ES module support in webpack configuration
  - Whitelisted Mermaid v11 dependencies as ES modules
  - Added .mjs extension support
  - Disabled minification for compatibility
- Fixed native module loading issues
  - Created proper bindings for ced, fontmanager, and native-keymap
  - Disabled ASAR packaging to allow module access
  - Copied native .node files to expected locations

  - Fixed initialization timing issues

Most diagram types now render correctly on first load.
Known issues: gitGraph and pie charts need additional work.

- Added pie chart textPosition setting (0.75) to fix rendering
- Maintains strict security level for other diagrams
- No impact on other diagram types

- Removed pie chart textPosition config that was causing block diagrams to fail
- Restored baseline Mermaid v11 configuration
- Most diagrams now work correctly

Known limitations with Mermaid v11:
- gitGraph: Not rendering (v11 compatibility issue)
- pie charts: Not rendering (needs different approach)
- block-beta: Experimental feature, may have v11 issues

- Increased DOM ready delay from 10ms to 50ms
- Added layout recalculation trigger (offsetHeight)
- Added post-render delay to ensure completion
- Fixed ESLint issues with no-unused-expressions

This should resolve the issue where diagrams required clicking
to render on initial file load.

- Increased pre-render delay to 120ms (was 100ms)
- Increased post-render delay to 120ms (was 100ms)
- This should ensure almost all diagrams render immediately on file open

…ming

- Replace sequential diagram rendering with batch processing
- Add 200ms DOM ready delay for better stability
- Implement triple requestAnimationFrame for forced repaints
- Add fallback individual rendering if batch fails
- Force explicit visibility styling for consistent rendering
- Most diagrams now render immediately on file open

… tests

Major upgrade:
- Electron 18.0.4 → 41.0.2 (latest stable)
- electron-builder 23 → 26.8.2, electron-rebuild → @electron/rebuild 4.0.3
- electron-updater 5 → 6.8.3, Playwright 1.21 → 1.58.2
- Mermaid 11.11.0 → 11.13.0

Mermaid rendering fixes:
- Fix __name polyfill for webpack code-splitting (pie/gitGraph were broken)
- Fix edge label text contrast for light and dark themes
- Surgical themeVariables: only override what mermaid gets wrong
- CSS overrides in default.css for edge labels and dark mode lines
- Ad-hoc codesign app-builder-bin to fix OSX/AdLoad false positive

New themes:
- Neon Editorial (light) — WIRED magazine inspired, vivid neon accents
- Neon Editorial Dark — ink-black with electric cyan/magenta
- Ashley (light) — soft pastels on warm paper
- Ashley Dark — deep Victorian bottle green with gold accents
- Background accent picker for all four new themes
- Prism.js syntax themes for dark variants

Build fixes:
- electron-builder.yml: extraFiles → extraResources (codesign fix)
- electron-builder.yml: Linux desktop entry schema update for v26
- Linux targets now include arm64 architecture
- webContents.print() callback → Promise for Electron 41

Testing:
- Playwright e2e test suite for mermaid rendering (16 diagram types)
- Node.js parse-level test (temp/test-mermaid-parse.mjs)
- Comprehensive mermaid test document (temp/test-mermaid-all-diagrams.md)

…ments

Contrast enforcement:
- Add automatic WCAG 2.1 contrast ratio checker that runs after every
  mermaid render — walks all SVG text elements, computes luminance
  contrast against detected background, flips to black or white if
  ratio < 4.5:1 (AA threshold)
- Detects backgrounds from parent rects/polygons (including inline
  styles), foreignObject backgrounds, and falls back to page canvas
- Works across all themes and accent colours automatically

PDF/HTML export fixes:
- Fix mermaid export: use textContent instead of innerHTML for v11
  compatibility (mermaid.run() reads textContent, not parsed HTML)
- Add startOnLoad: false and parse() validation before run() in export
- Individual diagram rendering with suppressErrors so one failure
  doesn't block the rest

Mermaid themeVariables:
- Stop overriding node text colours (primaryTextColor, nodeTextColor
  etc.) — let mermaid's own themes handle node contrast correctly
- Only override edge label backgrounds and specific label colours

Testing:
- Add export e2e test: validates 28/28 mermaid diagrams render as
  SVGs in HTML export
- Add printToPDF test: validates PDF buffer is produced
- All 8 e2e tests pass (export, mermaid, launch, XSS)

Add download section for v0.17.2-ea1 with direct links to GitHub
release assets for macOS (ARM64 + Intel) and Linux ARM64.

Native modules (ced, keytar, native-keymap, fontmanager-redux) must be
compiled on the target platform. Only macOS ARM64 build is valid from
a macOS ARM64 host. Other platforms require building from source.

…torage

Add hex colour validation (isValidHexColor) to all paths where accent
colours from localStorage are injected into CSS:
- applyAccentColor() rejects non-hex values
- storage event listener validates before applying
- applyAccent() delegates to validated applyAccentColor()

Prevents CSS injection if localStorage is compromised by another context.

Build fixes:
- Update node-abi resolution from ^3.8.0 to ^4.28.0 (required for
  Electron 41)
- Add rebuild.js wrapper that uses @electron/rebuild API directly
  instead of CLI (avoids yargs ESM issue on Node 22)
- Graceful rebuild failure — doesn't block yarn install
- Update README with Node 22 requirement, nvm instructions,
  troubleshooting guide

Theme menu:
- Add Neon Editorial, Neon Editorial Dark, Ashley, Ashley Dark to
  the File > Theme menu (were only in Preferences, not the menu bar)
