/* ==========================================================================
   Teams Presence Tracker - zentrales Stylesheet

   Saemtliche Farben liegen als CSS-Variablen vor (Auftrag Abschnitt 41).
   Die Statuspalette wurde fuer hellen und dunklen Modus auf Unterscheidbarkeit
   bei Farbfehlsichtigkeit und ausreichenden Kontrast geprueft. Status wird nie
   allein ueber Farbe vermittelt: Badges tragen Punkt und Text, Offline einen
   Ring, "keine Daten" zusaetzlich eine Schraffur.
