Authentication in this beta creates or validates Gymwolf sessions through the current `gymwolfSessions` flow and reads user data through the existing `api/gymwolf/*` routes.
Workout history, exercises and profile fields shown in `/new` are served from the shared FitQ PG-backed Gymwolf compatibility layer rather than a separate beta database.
The canonical site-wide privacy notice still lives on the main privacy page. This beta page exists to explain the technical rollout surface, not to replace the main legal document.
