Label

Radix Label renders a `<label>` and stops a double-click from selecting the
label text. Disabled dimming is pure CSS: `peer-disabled:` needs the control
to be an earlier sibling carrying the `peer` class (Checkbox, Radio Group
items and Switch already set `peer`), and
`group-data-[disabled=true]:` reads a `group` ancestor's `data-disabled`.

**Pebble (2026-11-03).** Kept the 14 px medium label and its peer/group disabled dimming; tightened tracking slightly. Added optional `required` (a muted, `aria-hidden` asterisk; the control carries `required` itself so assistive tech hears it once) and `hint` (12 px muted qualifier at the row end via `ms-auto`). A whitespace text node before the hint keeps the accessible name spaced ("Job title Optional"); flex layout drops it visually.
