The store frames.

Exactly the screenshots shipped to App Store Connect — the five frames of one continuous story: your own apps, built by chat.

Chat frame: the user asks Fa to build a personal weather app with a dashboard widget; tool-call tiles build it and open it
01 · the ask Your own apps, built by chat — describe an app and Fa builds it.
Apps frame: the launcher home grid with a live weather widget tile and the mini session-chat bar
02 · the dashboard Live widgets from the apps Fa built for you, right on the home screen.
In-app frame: the weather app open with the Fa session chat sheet pulled up over it
03 · Fa inside “Add a weekly forecast” — chat and tweaks without leaving the app.
Media frame: an inline generated wallpaper, a video clip tile and a voice-summary player in chat
04 · media Wallpapers, voice summaries and clips — generated inline in the chat.
Providers frame: the provider settings with keys stored in the Keychain
05 · providers Any provider — keys stay in the Keychain.

These PNGs are NOT hand-copied: the deploy copies them from the committed golden suite (flutter_app/test/goldens/store/en/ios/, generated by flutter test test/golden/store_screenshots_test.dart --update-goldens), and a CI test pins the page to the golden set — the site assets never drift from the store assets.
