 * TimePicker — an `'HH:mm'` (24-hour) time field built on `Singleselect` over a time grid generated from
 * `step` (minutes). Discriminated by `clearable`: `true` allows clearing to `null` and shows an X button;
 * `false` requires a value. An out-of-grid `value` is injected into the list so it always renders. Emits
 * the picked `'HH:mm'` string via `on.change`.
