An active-time descent where the aperture wave runs in real time.
PULSE arts hit hardest at the crest;
NULL arts peak in the plateau. Time your confirm to the wave.
The spiral's spans are phase-gated: pulse-spans are solid only
at the crest, null-spans only in the dark. Ride the rhythm down.
Descend, survive, bank echoes, and spend them in the Sanctuary
to go deeper next run. Every 5th floor: a Warden.
SHIFT the wave to steal phase advantage — legal only at A = 0.
