/* Spielinsel-Erklärvideo auf /referenzen/, /app-entwicklung/ und /spielinsel/
   Rahmen für das Querformat (16:9) und das Hochformat (9:16 im Handyrahmen) plus Pause-Knopf.
   Gleiche Haltung wie die WIRZEIT-Bühne (assets/referenzen-wirzeit.css): Haarlinien, Mono-Etiketten,
   Bernstein als einzige Auszeichnung. Laden und Abspielen regelt assets/referenzen.js
   (data-wz-stage / data-wz-video / data-wz-toggle): Quellen erst, wenn die Bühne sichtbar ist,
   stumm in Schleife, bei prefers-reduced-motion nur auf Knopfdruck.
   Auf der hellen Landingpage (/spielinsel/, body.help-page) andere Rahmen- und Textfarben. */
