- Add minimal theme preload script to prevent FOUC
- Fix favicon path to use base variable for GitHub Pages
- Theme script only sets data-theme attribute (no color mode)
- Maintains SSR/client consistency while eliminating flash
Fixes:
- Hydration mismatch error from localStorage access before Vue mount
- Favicon 404 on GitHub Pages deployment
- FOUC when theme applies after hydration
The new script is minimal and safe:
- Runs synchronously in head (before render)
- Only reads localStorage and sets attribute
- Matches what ThemeSwitcher.vue will do after mount
- No DOM manipulation that could cause mismatch
