+Creates (or reuses) a room with all 6 gate slots filled, roles assigned, and `table_status=SIG_SELECT`. Prints one pre-auth URL per gamer for pasting into 6 Firefox Multi-Account Container tabs.
+
+```bash
+python src/manage.py setup_sig_session
+python src/manage.py setup_sig_session --base-url http://localhost:8000
+python src/manage.py setup_sig_session --room <uuid>   # reuse existing room
+```
+
+Fixed gamers: `founder@test.io` (discoman), `amigo@test.io`, `bud@test.io`, `pal@test.io`, `dude@test.io`, `bro@test.io` — all created as superusers with Earthman deck equipped. URLs use `/lyric/dev-login/<session_key>/` pre-auth pattern.

 - Exclude channels tests: `python src/manage.py test src/apps --exclude-tag=channels`
 - Channels tests only: `python src/manage.py test src/apps --tag=channels`
