Square form field with a mono uppercase label and a vermilion focus border. One component covers input, textarea and select.

```jsx
<Input label="Work email" required placeholder="you@agency.gov" />
<Input label="Message" as="textarea" />
<Input label="Partnership interest" as="select" options={["Reseller", "Integration", "Advisory"]} />
```

Labels use DossierLabel automatically; the required marker is a vermilion asterisk. Corners stay square; the only state change is the border colour on focus.
