DESIGN BRIEF: sun-moon-arch celestial — the brief asked how sun and moon coexist over a Sahyadri hill without defaulting to tarpa spiral because circles appear in the sky. Sun-moon-arch places both luminaries in the upper register framing a triangle hill ridge, with circle-canopy trees along the crest like classical forest grammar. What we refused: tarpa musicians, concentric dance rings, perspective depth on hills, multicolor sky fill. What we kept legible: paired sun and moon circles, triangle hill silhouette, dot-canopy trees, sparse walker dots, hut square anchoring village scale. Light-mid density (~48% fill) preserves ochre air between celestial arch and hill so the scene reads as cosmic pause, not crowded festival poster.
