/**
 * Video Player Styles - Hearth Theme
 *
 * Based on the CourseFuture shared video player (controls, container)
 * combined with the proven IPV scene-based template CSS.
 *
 * Architecture:
 * - .video-player: outer container with controls (rendered by VideoPlayer class)
 * - .video-scene: each scene with layered rendering:
 *     .scene-background (image with Ken Burns)
 *     .scene-overlay (semi-transparent gradient)
 *     .scene-content (heading + bullets)
 * - Template variations via data-template attribute on .video-scene
