   Loaded on top of main.css, so it inherits the site palette (--primary,
   --secondary, --light, --dark) and the light/dark body gradients. Only the
   pieces that do not exist on the main pages are defined here: the payment
   card grid and the QR modal. Everything else (.header, .language-dropdown,
   .theme-toggle, .main-container) is reused from main.css unchanged.
