明度グラデーションカフェ：入口から奥へと徐々に暗くなる

Design a long narrow cafe whose colour deepens steadily from front to back. Show the street end in the palest wash of a single hue — a barely perceptible blush — and the rear in the fully saturated version of the same colour, with three or four intermediate steps between, each occupying one structural bay so the change reads as intentional. Detail the transitions as clean vertical joints aligned with the bays, never blended. Carry the gradient across the ceiling too, and keep the floor constant in a mid-tone terrazzo so the shift lives only in the vertical planes. Detail the furniture in the matching tint per bay, so sitting deeper means sitting inside a deeper colour. Show the counter placed exactly at the midpoint where the colour is halfway. Light the front with daylight only and the rear with warm concealed sources, so perceived brightness stays even while the colour intensifies. Photorealistic, subtle, tonal, eye-level view down the length.
