The fifteen-minute play door

A small bright low door set in the wall of a much heavier work-chamber. Child-height handle. Soft daylight spill through the doorway into the darker work-room. Substrate enforces: this door only opens for fifteen minutes and only for play that produces nothing. For burnout_acute users the door appears closed and unoperable — substrate surfaces the hum-silence first. NOT gated (counter-indications act at policy level, not place level).
