The problem
Your mobile users are downloading 1.8MB images on 4G. That's why they bounce.
"Our mobile conversion is 40% lower than desktop. We traced it to page load time — product images average 1.8MB each. We're sending desktop photos to mobile phones."
Both sides run simultaneously — real API calls, no mocks
