Macro τ-Crystal

The τ-macro-crystal is the cosmological-scale crystalline regime — the macroscopic phase counterpart of the microscale crystal regime (PG-O08), arising in book-V's macro-phase-transition setting (V.D113). It is the τ-categorical home of large-scale ordered structure and the prototype for macroscopic phase identification on the cosmological τ-base.
