Pôster de Viagem da Rota da Relíquia Flutuante

Convert the input city travel photos into a vertical 3:4 before-and-after comparison poster. The top half, about 50%, keeps the real city travel photography, accurately preserving the key facts of roads, ruins, bridges, buildings, ridgelines, or waterfronts. The bottom half, about 50%, is translated into "FLOATING RELIC ROUTE". The bottom half uses a warm ivory fiber paper base with large continuous negative space. From the photo, extract only one slightly curved road, river, coastline, or street path as the main axis. Along the path, place 3 to 6 landmark components from the photo, with obvious scale jumps and slight contact shadows between components, like floating travel relic specimens. Do not draw it as a regular map, coordinate grid, or ticket collage. Colors are limited to ivory, lime, ink black, low-saturation ochre, and mineral blue. The title should only be "RELIC ROUTE". The center line should be clear. Do not include unrelated landmarks, logos, watermarks, fake Chinese, garbled text, or original/AI image marks.
