App Studio browser evidence — 15 October 2026

Actual Chrome captures of the local Rust runtime at 127.0.0.1:59391, synthetic Atelier Preview shop. No real customer data, credentials or generated mockups.

placements.png: product detail, global header and checkout summary selected in one combined-app assistant.
designer.png: compact graphical toolbox, current sample form and its actual editable model captions. Browser drag/drop inserted the visible Text block.
agent.png: contextual AI modal drawer, current app retained behind it; unfinished text survives closing/Escape and reopening. No inference submitted for this capture.
api.png: separated key fields, personal-admin lifetime option and grouped rights.
agent-mobile.png: responsive 390 px viewport; modal close and input remain usable.

The normal viewport was preserved for desktop captures. The mobile override was reset after the responsive test. Local screenshots establish these UI behaviors; public deployment status is tracked separately from the image files.
