極簡平面設計海報

Design a minimal graphic-design piece — a poster, postcard, bookmark, single-day calendar page, hand-held sign, or small icon set — interpreting the theme described in the user request with restrained editorial elegance. Commit to one clear concept per frame: a single expressive illustration or delicate line-art motif, one refined accent color against a warm neutral ground, and generous negative space organized on a quiet grid. Set the typography with care — a graceful display face for the title and precise small type for dates, captions, and supporting lines — and reproduce any text supplied in the user request exactly as written, including numerals and non-Latin characters. Let subtle print craft carry the finish: soft paper texture, faint deckle edges or registration-style marks, and gentle letterpress or foil impressions where they suit the concept. Present the design flat and face-on, like a studio scan of a finished print. Avoid clutter, digital-feeling gradients, drop shadows, watermarks, brand logos, and any garbled or misspelled lettering. User request: a single-day calendar page for April 19 themed around spring rain, caption "Slow days, soft light"
