+## Git Workflow
+
+- **`development`** is the working branch — all new work starts here
+- **`main`** is deployment-only — never commit directly to `main`
+- Merge `development` → `main` only when code is ready to deploy
 
 ## Project Rules
 
 - Functional components only — no class components
 - All styling via Tailwind utility classes — no CSS modules or inline styles
-- Dark mode by default; use Tailwind dark-mode utilities and the CSS vars (`--background`, `--foreground`) defined in `globals.css`
+- Dark mode by default; use Tailwind dark-mode utilities
 - Keep components small and single-purpose
 - Prefer readability over cleverness
 - Do not add features unless explicitly asked
