 * Tuning knobs for the custom auto-quality monitor. This monitor only runs
 * when hls.js ABR is not in charge, i.e. when the `source` prop is a
 * user-provided `Source[]` profile list (mp4 or per-profile m3u8 URLs).
 * For a single master m3u8 URL, hls.js handles adaptive switching natively
 * and this config is ignored.
 *
 * All fields are optional when passed through the `autoQualityConfig` prop;
 * missing fields fall back to DEFAULT_AUTO_QUALITY_CONFIG.
