/* =========================================================================
   Angel Invasion — DBAT26 Kampagnen-Microsite
   FARBPALETTE: offizielle DBAT26-Farben (von Martin bereitgestellt).
   TODO: DBAT26-Branding einsetzen — offizielles DBAT26-Event-Logo (nicht
   BAND-Logo) fehlt noch (siehe .event-label in index.html). Pixelfont bleibt
   bewusst "Press Start 2P", unabhängig vom sonstigen DBAT26-Schriftbild
   (siehe Master-Prompt 1a).

   Kontrast-Hinweis: Die reinen Markenfarben Cobaltblau und Kirschrot sind auf
   dem dunklen Seitenhintergrund zu dunkel für WCAG-AA-Text/-Rahmen (< 3:1).
   Deshalb: echte Markenfarben (--dbat-*) für große Flächen (Buttons, Canvas-
   Sprites vor fast-schwarzem Spielfeld) — dafür aufgehellte Ableitungen
   (--color-primary-light, --color-danger) für Text/Rahmen auf dunklem Grund.
   Alle --color-* Text-/Rahmenkombinationen unten sind gegen ihren jeweiligen
   Hintergrund auf >= 4.5:1 (Text) bzw. >= 3:1 (Rahmen) geprüft.
