# React component builder

When asked to create a new component:

1. Place it in `src/components/<Name>.tsx` unless told otherwise.
2. Use `forwardRef` if it accepts a `ref` prop.
3. Type props with an exported interface named `<Name>Props`.
4. Style with Tailwind utility classes; no `@apply` outside of `globals.css`.
5. Add a colocated test `<Name>.test.tsx` covering the happy path
   and one edge case.

Avoid:
- `React.FC` (prefer typed function declarations)
- Index re-exports unless explicitly requested
- Inline objects in JSX props (extract to `useMemo` if needed)
