/*
 * Grundlage für Galerie und Dashboard.
 * Leitlinien (nach Apples Gestaltungsprinzipien):
 *  - Rückmeldung sofort beim Drücken, nicht erst beim Loslassen
 *  - Bewegung nur über transform/opacity, kurz und ohne Nachschwingen
 *  - Laufweite und Zeilenabstand hängen von der Schriftgröße ab
 *  - Schwebende Leisten aus durchscheinendem Material statt harter Ränder
 *  - Systemeinstellungen respektieren: weniger Bewegung, weniger Transparenz, mehr Kontrast
