/* Shared arcade chrome: back-to-arcade button + footer bar.
   All pages use the same flat, full-width bottom bar:
     [← Arcade]  Home · Privacy · USA · © STARSOFT LLC. STAR TROOPERS™  [Donate]
   with the Donate pill at the far right. Game pages put the back link
   inside a <footer class="site-footer"> element; the landing page's
   footer has no back link (it is the arcade home).

   --arcade-footer-h is the single source of truth for the bar height
   (content 26px + iPhone home-indicator safe area). Any game control
   anchored near the bottom of the viewport must add this to its
   `bottom` value so it never lands under the bar. */
