/* ============================================================
   Calendar+ — design tokens
   Palette: Mist (cool light bg) / Void (dark bg) / Aurora (primary
   accent, violet) / Ember (secondary accent, warm coral — reserved
   for "today" + important markers only, never decorative).
   Type: ui-rounded for day numbers & headings (distinct, native-
   feeling, zero network cost) · system-ui for body/UI chrome.
   Signature: the "today" cell — a slow conic-gradient halo ring
   around the date number, and a mini stacked bar per event instead
   of a plain dot, so category color reads clearly at a glance.
