DESIGN BRIEF: The layout problem was legibility at rotation speed — a cosmic wheel that reads as mandala, not decorative plate. Tantrik yantra grammar from Ranti lineage solves it: concentric rings with a cross-axis spoke structure so each quadrant gets its own cell without breaking fourfold symmetry. Fish orbit the centre because matsya already carry fertility and cyclical abundance in Mithila panels; here they become the motion vectors — two swimming inward, two outward — so the wheel feels like it turns even though every line is static. Peacocks anchor the four corners as rangoli guardians, a catalog brief I took literally: bold outline wheel in the middle, corner birds facing in, geometric border bands holding the field like an Aripana floor diagram scaled to wall height. Flat vermillion and indigo fills carry the Tantrik palette — less narrative than Bharni deity scenes, more visual mantra — while cross-hatched indigo quadrant grounds add texture without Kachni's full sky takeover. The sawtooth and zigzag borders echo chakra-segment geometry named in the classical catalog: universe cycle as repeatable folk pattern, not abstract cosmology lecture.
