## Best Practices
- Pick `<Textarea>` for content that wraps to multiple lines (commit messages, descriptions, notes); use Input for a single value like a name or domain.
- Set a generous default `rows` and grow only when the surface has vertical room; don’t let the field push primary actions below the fold.
- Validate on blur and pass a string to `error` to render the inline message; the validation replaces helper text on failure.
- Trim leading and trailing whitespace on submit so empty newlines don’t pass a `required` check.
- Labels are short Title Case nouns (`Description`, `Release Notes`); placeholders show an example value, not instructions like `Enter a description`.
- Validation names the field and constraint, ends in a period, and skips `please` (`Description is required.`, `Release notes can’t exceed 500 characters.`).
- Render helper text as a sibling `<p>` linked through `aria-describedby`; sentence case, one sentence, with a period.
