Fixed FOUC (Flash of Unstyled Content) issue with dark mode:
**Problem:**
- Page would flash light theme before switching to dark
- localStorage check happened after React hydration
- Caused jarring visual experience
**Solution:**
- Added blocking script in <head> that runs immediately
- Checks localStorage and system preference synchronously
- Applies 'dark' class before any rendering
- Prevents flash completely
**Technical Changes:**
- Inline script in layout.tsx head
- Runs before React hydration
- Added suppressHydrationWarning to html tag
- ThemeToggle now reads from DOM instead of re-setting
- Wrapped in try-catch for safety
**Result:**
- No more flickering on page load
- Smooth theme experience
- Works with both saved preference and system default
- Instant dark mode application
