/**
 * Schul-Podcaster - Gemeinsames Stylesheet
 * Version 9.2 - Studio Edition (durchgaengig dunkel)
 *
 * Wird von index.html (Startseite, Login-Dialoge, Admin-Dashboard) und
 * recorder.html (zusammen mit recorder-styles.css) eingebunden.
 *
 * Die Farbwelt stammt aus dem Login-Fenster (naechtliches Studio: tiefes Blau,
 * Indigo, Cyan, warmes Lampen-Bernstein) und gilt seit Version 9.2 fuer das
 * gesamte Produkt. Alle Farben stehen als Tokens unter :root - wer die Optik
 * aendern will, aendert dort und nirgends sonst.
 *
 * listen.html ist weiterhin eine eigenstaendige Datei mit eigenem <style>-Block;
 * sie spiegelt dieselben Tokenwerte (siehe readme/06-frontend.md).
