/**
 * AASM YouTube Playlist — front end.
 *
 * Colours are inherited from Astra's global settings (--ast-global-color-*),
 * so the Customizer still governs the palette. Fallbacks exist only for a
 * non-Astra context.
 *
 * The play badge is drawn in CSS. No image, icon font, or SVG file is
 * requested, which keeps the component free of any external dependency.
