Pre-session sound bath

Use this before you leave for the venue, not at the table. Find a quiet room, lie flat, headphones on, eyes closed. The tones move slowly from 174Hz to 432Hz; your only job is to keep breathing out longer than you breathe in. Players report a measurably calmer first level and fewer impulsive early-orbit decisions. Repeat on every day-one of a series and it becomes a reliable trigger: the sound means work is about to start.
