/**
 * BAP Performance — YouTube-Embed-Facade (EPIC-168).
 *
 * Ausschließlich tokenbasiert. Globale Tokens stehen ohne Fallback in `var()`;
 * die Default-Werte liefert `tokens-fallback.css` im Layer `bap-fallback`,
 * damit die Komponente auch auf Fremd-Themes ohne BAP-Tokens neutral aussieht.
 * Plugin-eigene Werte tragen den Prefix `--bap-performance-facade-*`.
