/* ============================================================
   CBI Events Calendar (C4) — native /events/ page styling.
   Ported from the POC reference (drawer variant only). Every class is
   prefixed `ec-` and all custom properties are scoped to
   `.events-calendar-app` so nothing collides with the site's global
   SCSS (which also uses .card/.btn/.title/.grid/.banner). Fonts are
   inherited from the site; --ec-navy is CBI brand navy.
