   MOBILE-FRIENDLY LAYOUT
   The site now uses a real "width=device-width" viewport, so
   every @media (max-width: ...) rule below applies naturally
   on phones/tablets — no forced desktop canvas, no manual
   pinch-zoom needed, no scaled-canvas side effects on fixed
   elements (header, video modal, WhatsApp button).
