Gamma-Explorer — cross-domain CREP Gamma = arctanh(eta)/sigma comparison frame

Interactive explorer comparing the GenesisAeon CREP inversion Gamma = arctanh(eta)/sigma across ten published domain calibrations (AMOC, Amazon, solar flares, Cygnus X-1 jet, neural avalanches, BTW/Manna sandpiles, cellular metabolism, diffusive routing, Hikari PoR consensus). Every eta/Gamma value is copied from its source package's own published constant, spot-verified against the actual repositories -- not invented. Explicitly framed as a comparison coordinate system, not a claim of a universal physical constant. Part of the GenesisAeon interactive-sandbox series.
