/**
 * Server-side ad insertion strategy.
 *
 * Responsibilities:
 *  - Discover hls.js metadata TextTrack objects created by
 *    `enableDateRangeMetadataCues` / `enableID3MetadataCues`.
 *  - Subscribe to DOM `cuechange` events; parse SCTE-35 splice commands
 *    from active cues (DataCue ArrayBuffer path for ID3, or custom attributes
 *    for EXT-X-DATERANGE).
 *  - Track active ad breaks and emit IAB quartile events via `timeupdate`.
 *  - Report all lifecycle events through the configured `AdEventSink`.
 *
 * What this strategy does NOT do:
 *  - Fetch VAST/VMAP (no outbound ad-tagged network requests — ad-blocker-proof).
 *  - Render an ad <video> element (the content stream IS the ad stream).
 *  - Acquire a playback lease (the stream is continuous).
