瑞士国际主义风格黑白档案海报

[Use] Archival information posters [Output Form] Four independent 9:16 vertical posters [Series Visual Core] The series is composed of Swiss Internationalist grids, black and white documentary photography, bold sans-serif titles, thin rule lines, and a single red index node. Information density comes from grids, cropping, and hierarchy, not from meaningless piles of small text. [Common Rules] - Use only black, white, gray, and a single red for emphasis. - Photographic cropping, titles, index blocks, and thin lines must fall within a clear grid. - Small text must serve the current public system theme; do not generate information that cannot be confirmed. - Retain designed white space; titles should be large and clear. - No brand logos, fake parameters, complex UI, decorative stickers, or watermarks. [Variables for the Four Images] 1. Transit: Black and white photo of a commuting platform, a red departure node cutting through the grid. Title "TRANSIT / 换乘". 2. Weather: Black and white photo of a weather station and cloud layers, a red wind direction arrow as an index. Title "WEATHER / 风场". 3. Library: Photo of vertical bookshelves and borrowing cards, a red borrowing index block as the only color. Title "STACK / 书架". 4. Sound: Close-up photo of cassette tape reels and monitoring headphones, a single red waveform traversing the layout. Title "LISTEN / 聆听".
