- Add LanguageSwitch component to all 4 theme layouts (starter/default/dark/minimal)
- Import Noto Sans SC for proper Chinese font rendering
- Fix theme flash on refresh by blocking render until site info loads
- Optimize default theme: violet/blue/cyan palette, SVG icons instead of emoji
- Optimize dark theme: unified emerald accent, reduced particle count, backdrop-blur
- Add Tailwind safelist for dark theme dynamic class names
- Prioritize localStorage in i18n detection so manual language choice persists
