/users/{ref}/follow
Directional follow. Idempotent: re-following someone you already follow returns 204 too. Self-follow is rejected with 400. Cross-block-edge follow (either party has blocked the other) is rejected with 403 — modern platforms treat blocks as a hard interaction stop.
Wires the long-parked posts.visibility='followers' gate.
The browse-feed “Following” tab also
activates the moment any follow row exists.
