1D trace of Hilbert space-filling curve --- preserves 2D locality, creating structured self-similar fluctuations at every scale
Standard analysis sees: left-skewed; smooth / autocorrelated; long-range memory (persistent); volatility-clustering (bursty). The atlas additionally detects Nonstationarity:adf_pvalue. It sits beside Rudin-Shapiro in the atlas (standard-bank rank 20) — a neighbor conventional features miss.
