/* ==========================================================================
   LIVE VISUAL CALENDAR — component styles
   Used on calendar-only.html. Uses the same CSS variables (--surface,
   --border, --primary, --accent2, --text, --text-muted, etc.) already
   defined in assets/common.css, so it automatically matches whichever
   theme (light/dark) is active — no separate light/dark rules needed here.
