The /fb/share page can show its heading without any usable share control. Replace the injected v3.0 Facebook SDK widget with a normal button linking to Meta’s supported Share Dialog, using the configured app ID and the signed-in user’s public profile URL. The control renders as soon as account data is available and no longer depends on one-time SDK parsing.

Logged-out visitors get a sign-in link, and the page always exposes the public privacy policy.

Validation: two focused component tests pass (logged-out access and share-link rendering after account data becomes available); repository ESLint/formatting and git diff --check pass. Opened the real Share Dialog with Audius’s production app ID and verified the Facebook composer loads. No Facebook post was published.
