Subject: [PATCH] feat(ui): add custom theme override system

Create custom-theme.css for theme overrides that won't conflict
with upstream updates. The file loads after globals.css, so its
CSS variables take precedence.

This approach ensures:
- Zero merge conflicts on git pull (new file, not in upstream)
- Theme persists across upstream updates
- Easy to modify without touching upstream code
