# Usage:
#   ./scripts/xdocker-delete-user.sh <username>
#   ./scripts/xdocker-delete-user.sh <username> --yes   # skip confirmation
#
# Removes the User and related data (inventory, transactions, deposits,
# case-key progress, duel rooms they created). Nulls jackpot/duel winner
# pointers that referenced them.
