/* ==========================================================================
   app-header — WSPÓLNY header storefrontu (sklep + landing).
   Wydzielony z shop.css/storefront.css/layout.php, by landing.php (standalone,
   bez shop.css) mógł renderować PIKSEL-IDENTYCZNY header bez ciągnięcia
   globalnych resetów body/a/html (które rozjechałyby autorską typografię hero).

   Tokeny (--bg-card itd.) rozwiązują się na sklepie z :root w shop.css (więc
   dark-mode działa). Na landingu tokenów brak => używane są fallbacki (light).
