/* GDMM v1.3-clean · layout.css
 * Seitengerüst und allgemeine Seiten: .shell, .sidebar, .nav-*, .topbar, .content, .bottom-nav,
 * .mobile-menu sowie Übersicht (.hero, .streak-*, .module-*), Kurse (.course-*, .exam-*),
 * Profil, Simulation (.sim-*), Anmeldung (.login-*) und Administration (.admin-*, .moderation-*).
 *
 * Zustandsklassen auf <body>, gesetzt in render() (js/views/layout.js):
 *   gdmm-at-login        nicht angemeldet
 *   gdmm-keyboard-open   Bildschirmtastatur erkannt (Mobilnavigation wird ausgeblendet)
 *
 * Einbindung (Reihenfolge ist Teil der Kaskade, siehe index.html):
 *   tokens → base → layout → modals → forum → tnt → live-participant → trainer → presenter → ux → trainer-workspace → awards
 *
 * Mobile First: Die Regeln ohne Media Query beschreiben die Smartphone-Ansicht,
 * @media (min-width: …) ergänzt größere Bildschirme. Die Werte enden auf .02px (z. B. 750.02px),
 * damit sie lückenlos an die früheren Grenzen (max-width: 750px) anschließen – auch bei gebrochenen
 * Fensterbreiten durch Zoom. Verbliebene @media (max-width: …)-Blöcke enthalten Deklarationen, die es
 * nur auf kleinen Bildschirmen gibt (die Regel setzt dafür auf großen Bildschirmen keinen eigenen Wert).
