The feet tray learns hazards and the warp step

Two blind spots close. The active body — wizard or ridden mount —
standing on a dimensional-warp token gets a "step through the warp"
button in the feet tray, dispatching warpStep for the wizard and
creatureWarpStep for the mount (the command the RNRX troll report
earned). And whatever you stand IN shows as a warning chip: tacks,
slime, dust, a pit, the ooze — the near plane's last secrets told.
