/* ─────────────────────────────────────────────────────────────────────────
   Liminal Events — calendar view stylesheet

   Scope: the calendar view at /events/calendar/ — the alternate to the
   archive list, surfaced via the View toggle.

   Visual language: a month grid where each event renders as a tinted
   block on its day. Multi-day events repeat on each day in the range.
   Ongoing programs do not appear in the calendar (they have no date) —
   the list view's Ongoing section covers them. The view toggle remains
   visible so users can swap back.

   Honors the same --le-* Customizer variables as archive.css and
   single-event.css. Category accent colors are derived server-side from
   --le-accent via OKLCH and emitted as --le-cat-{n}-{tint|fg|bar}.

   No JS. Pure HTML/CSS. Mobile breakpoint collapses the grid to a
   stacked agenda (only days with events render).
