# Textarea

Follows: **Input & Control Treatment**, **Typography Application**, and **Interaction States** from `../principles.md`.

`Textarea` is the multiline companion to `Input`. Use it for authored or pasted text that must remain editable in place, such as Markdown source, instructions, or evaluator criteria.

## Rules

- Pair it with a persistent label. Placeholder text is only a format hint.
- It begins at a purposeful minimum height and grows by user resize, not by autoresize animation.
- Use the monospace family for code, Markdown, structured text, and prompts; create a rich editor only when syntax-aware editing is explicitly required.
- Follow the same border, focus ring, disabled state, and color rules as `Input`.
