Emphasize architectural material textures: brick courses, vertical wood grain, paving grids, pine needles, foliage, railings, and shadows through hatching. Keep the sketches cohesive as if drawn on a single travel sketchbook page, with realistic but slightly imperfect hand perspective and handwritten annotations. No photorealism, no clean CAD lines, no digital UI elements.","customization":{"ink_color":"cobalt blue","paper_color":"warm off-white"}}
