GET`/api/v1/newsletter/unsubscribe`

Unsubscribe

Mark the user behind this send-token opted out of the Weekly Brief. Idempotent : re-clicking does nothing harmful. Invalid/unknown tokens get the same friendly page (no enumeration leak). Test sends (user_id NULL) flip nobody. The page links back to /resubscribe with the SAME token so an accidental click is reversible in 1 click.

Authentication

Public endpoint: no key required. Anonymous quotas still apply (see Rate limits).
