YouTube's client-identity policy requires the Referer header on embed requests. Host pages that restrict their referrer policy (e.g. same-origin) strip it, and YouTube rejects the embed with Error 153. Setting referrerpolicy="strict-origin-when-cross-origin" on the iframe overrides the document policy for that request only, matching YouTube's own recommendation. Fixes #51

Fix
referrerpolicy="strict-origin-when-cross-origin"on the YouTube embed iframe so it still sends aRefererwhen the host page's own referrer policy would otherwise suppress it. Without aReferer, YouTube rejects the embed with Error 153 (per YouTube's client-identity policy, which itself recommends this exact policy value). See Embed fails with Error 153 when the host page suppresses theRefererheader #51 for the full root-cause writeup and evidence.Testing
<meta name="referrer" content="same-origin">to a course'sindex.htmlto simulate a host that restricts its referrer policy.Refererheader, YouTube returns Error 153.Referer(origin only), embed plays normally. Confirmed via DevTools network inspection — the iframe attribute overrides the document-level policy for that request only, so no other requests are affected.Posted via collaboration with Claude Code
