* feat: add GDPR cookie consent banner
Add a GDPR-compliant cookie consent banner that gates analytics (Google
Analytics) and functional cookies (comments) until user consent is given.
Features:
- Theme-consistent styling using CSS variables (light/dark mode)
- Settings panel with category toggles (necessary, analytics, functional)
- Consent stored in cookie for 365 days
- Google Analytics only loads after analytics consent
- Comments only load after functional consent
- Translations for all 32 supported languages
- Accessible with proper ARIA attributes and focus management
Configuration in hugo.yaml:
params:
cookies:
enabled: true
categories:
analytics: true
functional: true
When cookies.enabled is false, scripts load normally without consent gating.
Closes#412
* refactor: move consent-gated GA to cookies/analytics.html
Move Google Analytics consent logic to avoid shadowing Hugo's internal
`_internal/google_analytics.html` template.
Changes:
- Rename google_analytics.html → cookies/analytics.html
- Update head.html to conditionally load:
- cookies.enabled=true: cookies/analytics.html (consent-gated)
- cookies.enabled=false: Hugo's _internal/google_analytics.html
- Align cookies/analytics.html with Hugo's internal template:
- Support Privacy.GoogleAnalytics.Disable setting
- Support Privacy.GoogleAnalytics.RespectDoNotTrack setting
- Add UA- prefix deprecation warning
Note: Custom JS is required for consent-gated GA because Hugo templates
render at build time, but consent happens at runtime. We cannot call
Hugo's internal template after the user grants consent - we must
dynamically inject the GA script via JavaScript.

* fix: banner showSettings key
* style: indent comments/include
* Add missing article.alert translation back
* style: format i18n toml files
* style: indent head/head.html

* fix: improve Mermaid diagram implementation (#1213)
This commit addresses multiple issues with Mermaid diagram rendering
and adds significant improvements to the user experience.
- Fix `<br/>` tags rendering as literal text instead of line breaks
- Fix flash of raw mermaid code before diagram renders
- Fix Gantt chart rendering issues in dark mode
- Fix diagrams briefly showing during theme switch re-render
- Fix expand modal showing diagram left-aligned before centering
- Add fullscreen expand modal with pan/zoom functionality
- Add toolbar with zoom controls (zoom in/out, reset, fit to screen)
- Add keyboard support (Escape to close modal)
- Add per-diagram transparent background via `%%transparent%%` directive
- Add comprehensive configuration options:
- `look`: classic or handDrawn (sketch style)
- `lightTheme`/`darkTheme`: theme selection per mode
- `lightThemeVariables`/`darkThemeVariables`: custom theme colors
- `securityLevel`, `htmlLabels`, `maxTextSize`, `maxEdges`
- `fontSize`, `fontFamily`, `curve`, `logLevel`
- Switch from ESM to UMD bundle for faster initial load (~1s vs 2s+)
- Lazy-load panzoom library only when expand modal is opened
- Pre-render alternate theme during idle time for instant theme switching
- Cache rendered diagrams to avoid re-rendering on theme toggle
- Move all inline CSS to article.scss using SCSS nesting
- Extract helper functions for better maintainability
- Use data attributes and event delegation for cleaner handlers
- Reduce mermaid.html from 411 to 177 lines (57% reduction)
- Add comprehensive mermaid-diagrams example post with all diagram types
- Document all configuration options in hugo.yaml
* refactor: extract mermaid inline JS to TypeScript module
Move ~155 lines of inline JavaScript from mermaid.html partial into
assets/ts/mermaid.ts. The partial shrinks from 179 to 36 lines and now
only contains modal HTML markup and Hugo Pipes build/import logic.
- Deduplicate initWithTheme() and renderOffscreen() helpers
- Enable minification via Hugo Pipes js.Build in production
- Remove user-configurable mermaid version from params.toml
