2x2 grid, do this for 4 famous historical scenes in human history and 4 famous dishes: ∇·M = σ( EVENT_GEOMETRY )   // divergence source from event shapes M( x, y, t ) evolves via: ∂M/∂t + (v·∇)M = 0, where v = ∇(EDIBLE_FIELD)  Initial condition: M( t=0 ) = material_field( [CULINARY_MEDIUM] )   // all available ingredients  Transport rule: - Streamlines of v coincide with contours of the historical scene. - At each spatial point, M is the edible material that advected there. - No external mapping needed; the PDE ensures structural mimicry.  Output: macro plated scene, overhead key light, black ceramic dish.
