A browser-based companion to the original V1 Python model: BFUT source-modulated sky, primordial-like comparison sky, hybrid sky, and randomized control, with power-spectrum proxy and field slice visualization.
Default settings are tuned to reproduce the same qualitative V1 behavior: BFUT is perfectly correlated with the structured source field, the primordial-like field is essentially uncorrelated, the hybrid field shows intermediate correlation, and the shuffled control destroys spatial coherence while preserving amplitude scale.
