/**
 * Calendar field on top of flatpickr. The VALUE is always ISO `yyyy-mm-dd`
 * regardless of `field.date_format` (display only):
 *   - `date_mode: 'single'` (default) -> `string | null`
 *   - `date_mode: 'range'`            -> `[start, end] | null` (inclusive)
 *   - `date_mode: 'multiple'`         -> `string[]`
 * `min` / `max` bound the calendar; `disabled_dates` (ISO days or `a/b`
 * intervals) and `disabled_weekdays` (0 = Sun … 6 = Sat) grey days out — and
 * the engine re-checks them on validate, so the calendar is UX, not the gate.
 *
 * The calendar renders INSIDE the element (flatpickr `static`), so it lives in
 * light DOM like every other node and picks up a theme set on any ancestor.
 * Give a clipping ancestor (`overflow: hidden`) room, or it hides the popup.
 *
 * A footer under the grid carries **Today** (picks today — greyed out when
 * min/max/disabled rules exclude it) and **Clear** (empties the value). With
 * `field.enable_time` the first button reads **Now** (i18n key `now`) and picks
 * today at the current time, to the minute (seconds dropped), under the same
 * min/max/disabled rules; like Today it closes the calendar. Both
 * `await el.updateComplete` resolves only once the calendar is attached (the
 * lazy flatpickr load is folded into it), so hosts and tests need no extra wait.
 * Today / Clear go through flatpickr, so they emit exactly like a click on a day. `disableMobile`
 * keeps this calendar on phones too — never the OS date wheel.
