* 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.
