LAYOUT SKETCH — a bare thin-line layout guide for a tight built interior, a REFERENCE ONLY for geometry and placement: take from it the camera framing, figure placement, pose and size/depth order, AND the structure the figures sit inside — which fixed fittings this space has and how many of each, which fitting each body rests on or at, which side of a fitting the hands are on, what each body passes in front of and what it passes behind, where any reflective surface sits and what angle it faces. Those counts and relations are what the finished frame must still show. It carries ZERO visual style — every texture, material, light and all realism come from the text and the photographic references. Never let any line-drawing quality leak into the output.
