 * Calendar addon stylesheet.
 *
 * Loaded only while the addon is enabled — by the board's layout on a self-hosted board, and
 * by the React build's own add-on loader — so it is shared by both editions of the calendar
 * and has to stay honest about that. The split below is the whole of the arrangement:
 *
 *  * **`.fv-calendar*`** — the React build's `Calendar.tsx` proves these too. They are the
 *    accent hooks (the week's first and last column, an event chip's colour and hover) and they
 *    are written against the *React* theme's tokens, because those are the ones it has.
 *  * **`.fv-cal-*`** — the PHP page's own layout, for classes the React build never emits. A
 *    board's tokens are `--surface`/`--text`/`--border` where the React theme's are
 *    `--card`/`--foreground`/`--border` (the last one shared), which is exactly why the two
 *    cannot be in the same rule: `.fv-cal-*` names this board's tokens and nothing else reads it.
 *
 * The core sets `--fv-calendar-accent` on the calendar page from the "Accent colour" option, so
 * every rule below follows whatever the administrator picked in the add-on's settings.
