[LANDMARK] 照片叠加蓝图注释信息图模板

创建 infographic image of [LANDMARK]，把 real photograph of the landmark 与 blueprint-style technical annotations and diagrams 叠加在同一图像上。角落放 hand-drawn box，标题写 “[LANDMARK]”。使用 white chalk-style sketches 标注 key structural data、important measurements、material quantities、internal diagrams、load-flow arrows、cross-sections、floor plans，以及 notable architectural or engineering features。整体为 blueprint aesthetic：在真实照片上叠加 white line drawings，形成 technical/architectural annotation style 和 educational infographic feel，同时保留 real environment visible behind the annotations。
