Methodology. Seeded Mulberry32 PRNG → 64×64 value-noise lattice → fractal Brownian motion with optional domain warping → marching-squares contour extraction at evenly spaced iso levels. Renders to HTML5 canvas at devicePixelRatio for export. Commercial use:the PNG is yours; please credit "Tempered Cartography · Made in America" if you reuse the work in publications.
