极简线稿：单一笔画宽度与纯粹轮廓

Create an architectural line drawing reduced to pure outline. Show the building in axonometric or elevation using a single consistent line weight throughout — every edge, every opening, every step drawn with exactly the same thin black stroke, with no variation for hierarchy and no fill of any kind. Detail the drawing so that form is communicated entirely by which edges are drawn and which are omitted: no hatching, no shading, no tone, no texture, no shadow. Show the surroundings with the same restraint — a ground line, a few trees as simple outlined shapes, a figure as a plain contour. Keep the composition centred with a generous white margin on all sides. Detail a single tiny element in a solid accent colour as the drawing's only deviation, such as a doorway or a chair. Pure line drawing, black on white, uniform stroke weight, no fills, no gradients, no photorealism.
