/* WCV public marketing site — shared stylesheet.
   Brand tokens match the app's own established identity exactly (same
   values as the pre-Flutter boot shell that used to live in web/index.html,
   and the same colors _WCVLogoPainter/AppColors use in-app): primary blue
   #2563EB, teal accent #14B8A6, ink #0F172A, muted #6B7A8D, hairline
   #E2E8F0, tint background #F0F6FF. Nothing invented here — reused, not
   redesigned. System font stack only (no @font-face, no webfont network
   dependency) — this is a lightweight, fast-loading marketing site, per
   the ticket's own performance requirement.

   No JavaScript is required for anything this stylesheet drives: the
   mobile nav uses a checkbox + sibling-selector toggle, FAQ uses native
   <details>/<summary>. The one page with any JS at all (site/index.html's
   hash-redirect shim) doesn't touch layout. */
