Kumpir cross-section reveals fluffy potato with melting cheese and corn.

2x2 grid, 16:9, do this for 4 underrated street foods in europe: input = [ product ]

inference_cascade := derive the real layer stack (3–7) → each layer's actual thickness
   → its material and job → the one layer that is the selling point → whether the
   category cuts clean (blade) or tears (foam, bread)
hero_dna       := one unit sliced on a single flat plane, cut face square to camera,
                  intact exterior still visible at the edge so you read object then interior
strata_law     := layer thickness in the render is proportional to the real spec — a 2mm
                  layer cannot look the same as a 40mm layer. order is fixed and matches
                  the labels. every cut face shows interior structure different from that
                  material's exterior (open cells, crumb, weave, grain).
cut_honesty    := the cut behaves like the material — foam compresses at the blade, bread
                  tears, metal shows a burr, chocolate fractures. a laser-clean cut through
                  a soft material is a failure.
label_geometry := leader lines land on the exact layer named, no crossings, all labels on
                  one side, thickness in real units beside each
depth_cue      := the cut plane is lit slightly brighter than the receding interior
color_discipline := neutral ground + one signal color reserved for the hero layer and cta
imperfection   := one layer slightly compressed or displaced where the blade passed
frame          := 16:10; commerce chrome present — nav, price, add to cart
mood           := "so that's what's inside"

render: one screen where the interior sells harder than the exterior ever could.

forbidden — objects: invented layers, decorative gradient bands standing in for material
forbidden — look: uniform layer thicknesses, labels pointing between layers, identical
texture on cut face and outer surface, multiple contradictory cut planes, a soft material
cut like glass
