/* ============================================================================
 * app.css  –  das Aussehen des Editors (nicht des Kurses)
 * ============================================================================
 *
 * WOZU DIENT DIESE DATEI?
 * Sie bestimmt Farben, Abstände und Schriften der Werkstatt selbst
 * (Kopfleiste, Seitenliste, Editor, Export-Fenster, Anleitung ...).
 * Das Aussehen des fertigen KURSES steht in css/player.css.
 *
 * AUFBAU DER DATEI (in dieser Reihenfolge):
 *   1. Schriften und Farben (Variablen)
 *   2. Grundlagen
 *   3. Knöpfe und Formularelemente
 *   4. Kopfleiste
 *   5. Editor (Seitenliste, Seiteninhalt, Eigenschaften)
 *   6. Export-Fenster
 *   7. Vorschau mit Simulator
 *   8. Anleitung und Über-Seite
 *   9. Kleine Bildschirme und Drucken
 *
 * FARBEN ÄNDERN: Die wichtigsten Farben stehen im Block ":root" direkt unten.
 * Ändere dort z. B. --accent, und die ganze App übernimmt die neue Hauptfarbe.
 * ========================================================================== */
