 * would silently defeat `filled` and `borderless` and no gate would notice. Each variant therefore
 * receives exactly its own, and the other two never see it.
 *
 * `outlined` USED TO BE THE TWO UTILITIES `border-input bg-background` (gh#880). That is why
 * `--control-surface-background` / `--control-surface-border-color` — documented, published, and
 * reaching the whole select family through `.ui-control-surface` — reached neither Input nor
 * DatePicker: the utilities outranked the tokens by construction. It is a component CLASS now, so
 * the same two tokens paint every field in the library. No token was added; the existing pair just
 * has no hole left in it. See `.ui-control-outlined-surface` in control.css.

 * nothing: `border-input` is a utility, utilities are a later layer, and a later layer wins over
 * any specificity. In Chromium the warned field measured `rgb(144 135 127)` — the resting border —
 * with the component rule in place and no error anywhere. Painting it from a utility instead puts
 * the two declarations in the SAME layer, where `data-[status=…]` (0,2,0) genuinely outranks
 * `border-input` (0,1,0). It is also the mechanism the library already used for the invalid state
 * (`aria-invalid:border-destructive`), so the two states now paint the same way.
 *
 * The `--focus-*` reassignments stay in `control.css`: those are custom properties, and no utility
 * competes for them.
