"""Verify the "needs you" inbox and answer-back, in a real (headless) browser.

Feature: a session waiting on the user surfaces three ways — a count on the tab
title, a lit bell with a badge, and an inbox sheet listing it — and can be
answered from that sheet without opening the pane (a typed reply, or an empty
send to accept the default). This drives all of it against a real panel:

1. Mark a session waiting (as a hook would) and confirm the badge, the lit
   bell, and the "(1) CLIque" tab title.
2. Open the inbox and confirm the session is listed.
3. Type a reply, send it, and confirm it reached the session's shell and ran.

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

    ~/.cache/clique-visual/bin/python tools/inbox_check.py

Exit status is 0 on pass, 1 on fail.
