export function Greeting({ name }: { name: string }) {
return
Hello, {name}!
} ``` ## Patterns - Progressive enhancement for forms - Component primitives over ad‑hoc utilities ## Testing - RTL for units, Playwright for E2E ## Resources - Related: design-systems - Related: headless-ui - Related: typescript - Related: propsShare this post
