石砌候车亭：粗石墙与厚重的阴影

Design a bus shelter built from local stone, heavy and rooted. Show thick walls of roughly squared rubble stone laid in irregular courses with a deep raked joint, the stones varying in size and tone from warm grey to ochre, their faces left as split by the mason. Detail the wall thickness as substantial — 400 millimetres or more — so the opening reads as a deep aperture with a real reveal, spanned by a single heavy stone lintel. Show the roof as large stone slabs laid directly across, overlapping slightly, their edges rough and their upper surface uneven. Detail a bench formed as a single long stone slab set into the wall on stone corbels, its top worn smooth. Show moss and lichen establishing in the shaded joints and a fern growing from one crevice. Detail the interior as noticeably darker and cooler than outside, with the light from the opening falling sharply onto the floor. Set it on a mountain road with dry-stone field walls in the same stone continuing beyond. Photorealistic, heavy, grey and ochre stone, deep shadow, three-quarter view.
