/* ==========================================================================
   Fort Collins Public Media
   One stylesheet. No preprocessor, no framework, no build step.

   Design intent: this is a broadcast facility, not a startup. The look is
   editorial and high-contrast — heavy type, generous space, one signal color
   used sparingly for anything live or actionable. No gradients, no drop
   shadows, no rounded-everything. Rules and blocks do the structural work.

   To rebrand: change the tokens in :root. Nothing below hardcodes a color.
