+Übernahme fremden HTMLs erforderlich.
+
+Player werden nur für streng erkannte YouTube- und TikTok-URLs erzeugt. Aus der
+validierten Anbieter-ID baut Sendewerk die offiziellen Embed-Adressen selbst;
+gespeichertes oder fremd geliefertes Embed-HTML wird nicht verwendet. YouTube
+nutzt die datenschutzreduzierte `youtube-nocookie.com`-Adresse und den
+`start`-Parameter. TikTok erhält eine Startposition nach `onPlayerReady` über
+die dokumentierte Player-`postMessage`-API. Autoplay bleibt ausgeschaltet, und
+ein Inhaltswechsel ersetzt das Iframe vollständig.
