- Expand Theme type to catppuccin-mocha | tokyo-night | catppuccin-latte
- Export THEME_META with label, dark boolean, bg hex, primary hex per theme
- applyTheme toggles .dark and .theme-tokyo-night classes correctly
- toggleTheme cycles all three themes (Mocha -> Tokyo Night -> Latte -> Mocha)
- readStoredTheme falls back to catppuccin-mocha for old localStorage values
- Fix Layout.tsx: replace theme === 'dark' comparison with THEME_META[theme].dark
- Fix MarkdownBody.tsx: replace theme === 'dark' comparisons with THEME_META[theme].dark
Add ThemeContext with localStorage persistence and FOUC-preventing
inline script. Add theme toggle button in sidebar. Update status
badges, toast notifications, live indicators, and approval cards
with dark: prefixed classes for proper light mode rendering.
