export default function Example() {
  return (
    <div className="flex w-full max-w-md flex-col gap-1.5">
      <label htmlFor="example-reason" className="text-sm font-medium">
        Why reject this change?
      </label>
      <Textarea id="example-reason" placeholder="The agent sees this and tries again." />

No props.

Also takes the props of `React.ComponentProps<"textarea">`.

## Rules for using Candor UI

- Components take plain typed data. Never pass model output as HTML or render it as a link; messages are typed blocks.
- A control that can't be used says why: wrap it in `<Locked reason="…">`, don't just disable it.
- Don't show a value you don't have: leave it out (it renders as —) rather than guess. An estimate is labelled as one.
- Nothing is pre-selected in a decision a person makes, and the agent is named from your app's data, never from model output.
- Your app's words go in `LocaleProvider` (fixed strings) and `TermsProvider` (nouns); entity kinds and agent roles in `EntityKindsProvider` and `AgentRolesProvider`.
