/* ==========================================================================
   PlayArena admin console

   Visual idea: a sports ground is defined by its chalk lines. The interface
   borrows that — a 3px "touchline" marks the active nav item and section
   headers, and nothing else in the chrome competes with it. Everything is
   built on Bootstrap 5.3 custom properties, so `data-bs-theme="dark"` is a
   free, complete dark mode.

   The brand colour is injected from Settings at runtime; never hardcode it.
