|---|---|
| Flash of wrong theme on page load | Add inline script to <head> before hydration |
Using opacity for text variants | Use separate CSS token with correct contrast ratio |
Dark text (gray-900) on dark bg | Always test contrast; use --text-primary token |
| Hover states not visible in dark mode | Ensure hover has ≥3:1 contrast vs default state |
currentColor for icons | Verify icon color passes 3:1 contrast vs background |
