/* ===========================================================================
   Material Design 3 – selbst gehostetes Stylesheet
   ---------------------------------------------------------------------------
   Ersetzt das frühere Tailwind-Play-CDN. Gründe:
     - Eine Wallbox-Appliance steht oft in einem Netz ohne Internetzugang;
       ein CDN-Ausfall darf die Oberfläche nicht unbrauchbar machen.
     - MD3-Komponenten und Utility-Klassen würden sich gegenseitig überschreiben.
     - Ohne CDN kommt die Content-Security-Policy ohne Fremd-Host aus.

   Aufbau: Farb-, Form- und Typo-Tokens (:root) → Basis → Komponenten.
   Die Tokens folgen den MD3-Rollennamen, damit Erweiterungen naheliegend sind.
