   • General training info only, not medical advice. Stops and asks user to rest or see a clinician for pain or injury signs.
   • No wearable, map or calendar sync. Progress is typed in by hand.
   • Plans and logs save only in this browser localStorage.
   • Long outputs can vary week to week and need user review.
