BEFORE (App-Centric):
User: "I need to track my workout"
→ Opens phone
→ Finds HealthSync app  
→ Navigates to workout logging
→ Fills out form
→ Saves data

AFTER (Agent-Centric):
User: "I just finished a 5-mile run"
Agent: "Great! Logged your run. That's a new personal best pace!"
→ Everything handled seamlessly via API
→ User gets value without touching phone
