and has picture content.

/**
* The P1/A1 camera in the real web console, in a real Chrome, for
* scripts/e2e-camera-snapshot.sh (BROWSER=1). Signs in the same way as
* e2e-camera-browser.ts. Reads pixel statistics and keeps no screenshot: the
* frame is the inside of someone's workshop.
*
* Results are `ok<TAB>label` / `FAILED<TAB>label`.
* Environment: APP_URL, SUPABASE_E2E_EMAIL, SUPABASE_E2E_PASSWORD, CHROME_BIN.
