Summary

Keep social sharing cards concise while preserving the original video title, creator credit, and YouLoop branding.

• Video og:title, Twitter title, and HTML title are the original YouTube title, without the - YouLoop suffix.
• Video descriptions are by <creator> · YouLoop when an oEmbed author exists, or YouLoop otherwise.
• Do not repeat the title or upstream description in the social byline.
• Keep og:site_name, thumbnails, canonical URL normalization, generic fallback metadata, and the picker response unchanged.

Verification

• Updated existing Node metadata tests for exact title/byline, author truncation and missing-author fallback, upstream description exclusion, and escaped social head tags.
• Updated the existing SSR social smoke assertion for the new title and description format.
• No new routine browser tests; existing metadata and smoke checks are appropriate, with no obsolete additional coverage retained.
• Reviewed correctness and cleanup at 54ab0349f1be60a69c3ab8fcf5d5afe46ebd769e; no actionable findings or code changes were needed.
• Local checks passed: pnpm check (zero errors/warnings), pnpm lint, pnpm test:clip (36), pnpm test:share-url (24), pnpm test:metadata (18), YOULOOP_RUNTIME_PROOF=1 pnpm build, and pnpm test:browser (36 Chromium/WebKit executions).
• Production-mode preview passed test:hosting (7) and test:social (9). Social smoke also passed with REQUIRE_VIDEO_METADATA=1, exercising live video titles and creator bylines rather than generic fallback.
• GitHub hosting verification and Vercel Preview passed at the same head.
• Broader advisory browser cases and the separate frame/timeline proofs were not run for this metadata-only change. Existing tests were updated in place; no tests were added or retired.

Follow-up

• Validate a fresh social card in the messaging app shown in the screenshot (some platforms cache Open Graph cards; a stale unfurl is inconclusive).
• Maintain maintainer-controlled merge.
