Can't log in on new mobile device, web, or one laptop.

I uploaded logs from the failing laptop instance at keybase/client#24176. On Android, entering my username results in a blank screen with a floating figure and no text. On the web, logging in sends me to my profile page, still logged out.

Start with the logs uploaded at keybase/client#24176 and compare them with the reported Android and web symptoms. Check the username-entry flow on Android and the redirect to the profile page on the web. Done means login works on the failing laptop, Android device, and web account.
