/* ============================================================================
   Random & Unfair Battlefields — landing page
   Rebuilt from design_handoff_landing_page. Every colour, size and spacing
   value below comes from that handoff; the desktop layout is the design to
   the pixel. The @media blocks at the foot are additions — the design is
   desktop-only and says so.

   ⚠️ --accent is the one theme knob. Everything gold reads it.
   ⚠️ No border-radius anywhere except circles. The design is square-cornered
      on purpose; adding a radius here changes the whole character of it.
