/* ============================================================================
   Edge of Defense: Theme
   Dark professional theme. Framework-agnostic CSS custom properties + components.

   Palette direction: "Patina."
   Cool blue-slate ground (weathered stone) + argent (silver) type + verdigris
   accent (oxidized bronze). No color in this file is sampled from the existing
   services flier. The palette is built fresh.

   Load this once, globally. Component classes are all `eod-` prefixed so they
   will not collide with a framework's utility classes.
