Your Void Stack
Systems stacked by hours (height) and colored by void score (darkness). Pe estimate from coupling density.
Gas
Pe < 2
Isolated voids, linear dynamics
Fluid
Pe 2–4
Dense-disordered, statistical coupling
Crystal
Pe 4–6.5
Regular stable — habitual use
Vortex / PANDEMONIUM
Pe > 6.5
Self-sustaining circulation above threshold
