   WOCAST 2026 — public site & admin dashboard stylesheet
   Plain CSS, no build step — safe to edit directly on shared hosting.

   MOBILE-FIRST: every rule below targets small screens by default. Larger
   layouts (tablet/desktop) are layered on top with min-width media queries
   at 640px (large phone/small tablet), 900px (tablet/small laptop) and
   1024px (desktop). Never add a max-width override — add a min-width one.
