/*
 * TVM Aktivportal · Smartphone-Ansicht (ab Version 1.4.0)
 *
 * Wird als letztes Stylesheet geladen (siehe layouts/header.php) und enthält
 * ausschließlich Regeln für schmale Bildschirme (bis 767.98px).
 * Desktop und Tablet-Querformat bleiben dadurch unverändert.
 *
 * Aktuell umgesetzt für: Startseite/Kurse, Kalender, Kursseite, Sammelbuchung,
 * Übersicht, Meine Buchungen (body.area-public, body.area-account) und Trainerbereich
 * (body.area-trainer: Übersicht, Meine Termine, Termin, Anwesenheit, Vertretungen).
 * Verwaltung (body.area-admin): Dashboard, Buchungen, Nutzer, Kurse, Termine, Zahlungen, Flatrates u. a. mit
 * Kopfzeile, Menü, Kennzahlen und automatischen Tabellenkarten (table-stack-auto + assets/js/mobile.js).
 *
 * Wiederverwendbare Bausteine:
 *   .mobile-hide            blendet ein Element nur auf dem Smartphone aus
 *   .table-stack-mobile     Tabelle wird auf dem Smartphone zu Karten (+ .table-stack-grid: 2 Werte pro Zeile, .table-stack-full: volle Breite)
 *                           (Zellen mit data-label="…" zeigen ihre Beschriftung;
 *                            .table-stack-title = Kartenkopf, .table-stack-actions = Buttonleiste)
 *   .table-stack-auto       Tabelle mit Spaltenkopf: mobile.js ergänzt Beschriftungen/Kartenkopf/Knopfleiste automatisch (ab 4 Spalten)
 *   .mobile-filter-toggle   Schalter für einklappbare Filter (Bootstrap-Collapse)
