Chinese Firefly Summer Night Poster

Goal: Create a serene Chinese seasonal poster about {argument name="solar term" default="小暑"}, with a translucent, ritual-like summer night atmosphere and refined editorial typography.

Canvas: Wide horizontal 16:9 poster, 1200 × 675 style composition. Use a warm ivory rice-paper texture with subtle fibers and grain. The background is divided into two calm high-key color fields: a large creamy off-white upper sky and a pale misty blue-green lower field, softly blended, clean and breathable.

Layout: Keep large negative space in the upper half. Place the main vertical title {argument name="main title text" default="小暑"} slightly right of center, very large, in dark blue-black Chinese calligraphy/serif type. Above it, add a hazy pale yellow-green circular moon glow containing exactly 2 celestial marks: one tiny white crescent moon and one tiny white star below it. Around the title, arrange exactly 4 slim vertical informational text columns: one to the left of the main title, one far left near the headline area, and two to the right of the main title. Add a small orange-red seal stamp below the main title.

Text content: Top left headline reads {argument name="headline text" default="流萤点夜"} in large dark ink Chinese characters. Below it, a smaller orange subtitle reads {argument name="subtitle text" default="夏夜流萤 · 微光如许"}. Beneath the subtitle place a short orange horizontal dash, then two small dark lines of Chinese body text: “萤火成诗” and “照见人间清凉”. Right side quote block uses oversized orange quotation marks and the quote {argument name="quote" default="白昼的热退去后，夏夜会把微光一颗颗交给你。"}. Bottom right footer reads “小暑 | 初候温风至 |” followed by a small orange circular mark, with smaller date text underneath: “07/07-07/22 | 农历六月初一至六月十七”. Keep all Chinese text legible and elegant.

Subject details: The lower third contains a hand-painted summer field growing upward into the layout: exactly 1 rustic bamboo fence running diagonally from lower left toward center, made of multiple vertical stakes and horizontal rails; tall reed leaves and grasses sweep diagonally across the scene; delicate wildflower stems rise from the left and center. Add exactly 10 visible fireflies with glowing yellow-green abdomens: 3 around the left flowering stems, 2 near the central title area above the grasses, 2 in the mid-right grasses, and 3 tiny glowing dots near the bottom field. On the far right, include exactly 1 traditional dark wooden house corner with a black tiled roof, a bamboo roll-up blind, and exactly 1 warmly lit window. Inside the window place exactly 1 small white ceramic vase with a thin plant branch. The house should occupy the right edge and bottom-right corner, partially cropped.

Visual style: Delicate watercolor and ink wash illustration, fine hand-drawn botanical detail, muted blue-green and dark teal foliage, warm yellow firefly light, soft atmospheric mist, restrained editorial design, antique Chinese book-cover feeling, high brightness, airy paper texture, no photorealism.

Constraints: Do not overcrowd the composition. Preserve the asymmetric balance: text-heavy airy upper area, organic illustrated growth along the bottom. Use exactly the counted objects specified above, avoid extra animals or people, no watermark, no logo, no modern UI elements.
