   WINBOX RACING — CORE
   The shared shell only: design tokens, reset, nav, mobile drawer.
   Extracted from winbox-racing.css so the news pages don't have to
   download the whole 46KB landing-page stylesheet.

   about-us.php still loads winbox-racing.css in full — it needs the
   hero, mosaic, carousel and FAQ rules that live there.

/* ══════════════════════════════════════════════════════════════
   PAGE TRANSITIONS
   Cross-document View Transitions: the browser snapshots the old page,
   loads the new one, and cross-fades between them — so navigating feels
   instant instead of flashing white.

   Pure CSS. No JS, no SPA router, no change to how pages are served, so
   the server-rendered HTML (and the SEO that depends on it) is untouched.
   Browsers without support simply navigate the normal way.
