Conversion de l'affiche géométrique ocre monumentale

Transform the input city travel photo into a vertical 3:4 before-and-after poster, with the top approximately 50% retaining the main commemorative architecture, towers, facades, plaza, and sky from the real photo; the bottom approximately 50% reinterpreting it as "MONUMENTAL OCHRE GEOMETRY｜Ochre-gold monumental geometry architecture poster style". In the bottom half, use dark gray architectural line drawing, pen hatching, woodcut-style shading, and fine halftone dots to reorganize the single main building from the photo; behind it, add one large-scale ochre-yellow circle, semicircle, or curved geometric color field, supplemented by no more than two cream white / charcoal black geometric shapes. Compress the plaza into a few flat color planes, keeping a few figures from the original photo as scale references. Warm gray paper, paper fiber, and old poster wear; the title should only read "MONUMENT". The bottom half must not be pure geometric abstraction or a whole-image filter; the center line must be clear; no ukiyo-e, 3D, logos, watermarks, fake Chinese, garbled text, or original/AI image corner marks.
