/* ============================================================
   Site-wide Navbar — "venue chrome"

   One component, theme-aware via CSS variables:
   · default        — dark rose (static/info pages, unchanged look)
   · scoreboard     — arena dark tuned to the LED board (amber)
   · climbing       — arena dark tuned to the comp board (rope pink)
   · page-home / page-config — warm paper chrome matching the
     light pre-game theme, with the game's accent on ink

   All component rules below consume the variables; themes only
   override variables, never component selectors.
