# A3 — Web 1440×1000, dark

Real app, real git, actual merged GitHub PR. Chromium 148 headless via agent-browser on Linux, no device emulation, DPR 1, font scaling 100%, system Inter, reduced motion enabled; same scroll position and JS wall clock frozen at 2026-11-03 03:00 UTC. Stills waited for network idle and fonts and passed byte-identical PNG checks 500ms apart. Full viewport, no crop. Stopped synthetic history was seeded via deferred message + stop RPC (no provider executed).
