Reproduce the Twitch login flow described for Edge and Firefox using SteamTools 2.8.6 on Windows 11, then inspect the relevant Twitch acceleration and login entry points. The payload names no source files or tests, so locating the responsible code is part of the investigation. Done means Twitch login no longer reports that the browser is unsupported, with a regression test or documented verification where the project permits.
