/**
 * OmidSession — Full IAB OMID (Open Measurement Interface Definition) integration.
 *
 * Integrates with the IAB OMID Session Client SDK, which must be loaded by the page
 * before ads play (e.g. <script src="omweb-v1.js"></script>).
 *
 * The SDK exposes:
 *   window.OmidSessionClient  — namespace containing AdSession, Context, Partner,
 *                               VideoEvents, AdEvents, etc.
 *
 * Spec: https://iabtechlab.com/standards/open-measurement-sdk/
 *
 * Usage:
 *   if (OmidSession.isAvailable()) {
 *     const omid = new OmidSession(adVideo, verifications, 'limited');
 *     omid.impression();
 *     omid.start(duration, volume);
 *     // … quartile calls …
 *     omid.destroy();
 *   }
