/* =========================================================================
   Codaluna · design.css — Tokens, Basis, Buttons, Editor-Farben
   Gestaltung „Stationskonsole“ (Oktober 2026): flache Flächen, feine Linien,
   ein Signalton (Amber) für Handlung und Position, Teal nur für Lumo und
   „geschafft“. Keine Verläufe, kein Leuchten, keine Emojis in der Oberfläche
   (Icons: src/js/icons.js). Schrift: Atkinson Hyperlegible Next, gebaut für
   gute Lesbarkeit (I/l/1 und 0/O klar unterscheidbar), Code in JetBrains Mono.
   Offline: alle Schriften liegen in /vendor/fonts.
