/* ============================================================
   Responsive — scale the whole games page uniformly down for smaller

   preserved exactly (navbar, board, sidebar, panel, gaps, fonts all
   scale together).

     1150–1299: zoom 0.82                (e.g. 1280px)
     1024–1149: zoom 0.74                (small laptops)
     ≤  768px : mobile layout (separate ruleset below)
   Also at < 1500px we tighten the gap between the board and the mode
