Mid-Autumn Moon Festival Poster

Goal: Create an elegant vertical Chinese festival poster for {argument name="festival theme" default="Mid-Autumn Festival"}, blending traditional ink-painting aesthetics with modern editorial layout. Canvas: Portrait poster, 3:4 ratio, deep midnight navy textured paper background with subtle grain, mottled ink wash, and aged print imperfections. Use a restrained palette of dark blue, warm moon gold, ivory, muted ochre, and small red seal accents. Layout: A huge detailed full moon dominates the upper left, cropped by the top and left edges, occupying about half the poster width and extending down to the upper-middle area. The moon should have realistic crater texture, parchment-gold coloration, and soft irregular edges. The right side is mostly dark negative space for typography. In the lower right, include a very faint traditional Chinese roofline and a dim circular lattice window pattern emerging from the darkness. In the lower left, place one delicate osmanthus branch rising diagonally upward with small golden blossoms and dark green-gray leaves. Text content and typography: Include exactly 7 distinct text groups: 1) left vertical Chinese date text near the moon reading “农历八月十五 — 月满人间”; 2) a tiny red crescent moon mark beneath that vertical date; 3) upper-right small English series label reading “Festival Poster Series — No. 08”; 4) large central-right Chinese brush calligraphy reading {argument name="main Chinese title" default="中秋"}; 5) small red rectangular seal beside the calligraphy reading “解锁”; 6) English title below the calligraphy reading {argument name="English title" default="Mid-Autumn Festival"}; 7) lower-left English keywords stacked in small caps reading “MOON / OSMANTHUS / REUNION”. Add one faint vertical handwritten Chinese poem column near the osmanthus branch and one small red square artist seal at the bottom-left corner; these should look decorative and partially faded rather than highly legible. Subject details: The osmanthus branch should be a single branch with multiple offshoots, thin woody stems, exactly 18 visible small five-petal golden blossoms, and about 10 muted leaves. The moon texture should feel tactile and photographic while still harmonizing with the painterly paper background. Visual style: Refined museum-poster composition, traditional Chinese festival mood, poetic, quiet, premium, minimal, asymmetrical balance, generous negative space, subtle letterpress texture, calligraphy on rough paper, cinematic moonlight. Constraints: Do not add people, animals, lanterns, food, or extra decorative objects. Keep the poster uncluttered. Preserve the exact count of 7 main text groups and one osmanthus branch. Make all text crisp enough to read except the intentionally faded poem column.
