"""Verify the board — sessions grouped by what they are doing — in a browser.

A session marked waiting lands under "Needs you"; a killed one lands under
"Stopped". The columns fill from workState, the same authoritative status the
sidebar uses, so this checks a card ends up in the right place.

Its own home, port and tmux socket; nothing touches a panel you are using.

Exit status is 0 on pass, 1 on fail.
