Create a finished vertical Chinese calligraphy exhibition poster, 3:4. Use an aged warm-ivory xuan paper sheet with visible long paper fibres, faint deckled-edge shadow, and a sparse pale-grey ink wash suggesting a pine branch in the upper left; a small vermilion square seal sits near the lower right of the title. Do not make a generic digital brush font. Exact rendered Chinese copy: “药食同源” Composition: keep at least 55% breathing room. Set “药食同源” as the sole largest headline, vertically stacked and centered, occupying 52% of canvas height. Each character is constructed as upright, slightly condensed East Asian commercial brush-display lettering, balanced and legible. Use controlled 3:1 thick-to-thin strokes: firm near-uniform stroke bodies, modest taper, decisive clean terminal landings, no dramatic flying harai. The characters are deep black sumi ink: wet glossy pooling at selected stroke starts, dense black cores, grey thinning passages where xuan fibres show through, individual bristle hairs at dry terminals, subtle capillary bleed into the paper. Use restrained dry-brush texture only at final terminals, with a compact wet ink landing on the final character. Add a hand-stamped vermilion seal bearing an abstract carved mark, not readable text. Soft raking daylight from upper left reveals paper relief and ink sheen; matte archival print, no neon, no gold, no photographic people, no Western serif proportions.
