Prototype only. No real login or database. Pick an account on the first screen. Each user has their own program, their own weight history, and their own lb/kg setting. Kris's account runs the clinical daily check-in (one-tap all-clear with a "Something's off" expander). Cherif's account runs a plain full-body program with no clinical gating. Machine weights are real pounds you type in, carried forward from your last session. Switch accounts from the top-left to see the data stay separate.
