 # Contributing
 
-1. Read the feature specification and plan under specs/portfolio-architecture-refactor/ before making architectural changes.
+1. Read README.md and the relevant source files before making a change.
 2. Keep portfolio content in src/content and avoid duplicating identity values in components.
 3. Run npm run check and npm run test:e2e before opening a pull request.
 4. Preserve accessible keyboard navigation, reduced-motion behavior, responsive layout, and the existing visual identity.

The contact limiter is intentionally an in-memory, per-instance guard suitable for low-volume portfolio traffic; a managed limiter would be the next step if abuse volume grows.
