"""
Management command for manual multi-user sig-select testing.

Creates (or reuses) a room with all 6 gate slots filled, roles assigned,
deck contributions wired, and table_status=SIG_SELECT.  Prints one pre-auth
URL per gamer so you can paste them into 6 Firefox Multi-Account Container tabs.

Deck contribution by role pair (same segment, levity vs gravity pole):
  PC & BC → Brands + Crowns     (levity / gravity)
  SC & AC → Blades + Grails     (levity / gravity)
  NC & EC → Trumps              (levity / gravity)

Usage:
    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
