shadcn's Textarea in Notchset, Archivo in a ruled box with the ink focus trace. TextareaField is the full instrument: a label row, a box that grows from 96 to 220px and then scrolls, a 24-dot token meter with an estimate and cost per run, and a helper that changes on focus.
pnpm dlx shadcn@latest add https://beautiful-ui.dev/r/textarea.jsonpnpm dlx shadcn@latest add https://beautiful-ui.dev/r/radix-nova/textarea.jsonFree, no account or key. Use the command for your project's primitives: a radix-*, new-york or default style in components.json is Radix, a base-* style is Base UI. With the @beautiful-ui registry added, @beautiful-ui/<name> picks for you.
The CLI adds the styles to the CSS file named in components.json (tailwind.css). Check that it points at your global stylesheet, that the project uses Tailwind CSS v4, and that the file is imported in your root layout. Installed by hand: paste styles.css into that file.
Import it and pass your content. The props that matter most are listed next.
