# Single source of truth for available arenas: the Free Play menu dropdown
# lists all of these, and Match/Spectate pick at random each session from
# those with "random" true. Training is exempt — training.tscn/
# training_elevated.tscn each keep their own fixed Arena child.
#
# Elevated-goal variants are Free-Play-only ("random": false) until a
# checkpoint trained on training_elevated.tscn is promoted — the current
# promoted bots (see main_menu.gd's DIFFICULTIES) were trained exclusively
# on floor-level goals and can't be expected to score on an elevated one.
# Flip a variant's "random" flag to true once that training/promotion has
# happened.
