怎麼填變量：標題和副標題可以換成中文，如"DNA 的鹼基配對 / DNA 雙螺旋近景"，標註同步改成"腺嘌呤 (A)""氫鍵"等。換別的分子或細胞結構時（如"ATP 分子""細胞膜磷脂雙分子層"），保留"背景 + 版式 + 標註數量限制"的寫法，把主體細節和 7 個標註換掉。

示例圖與描述一致：白底中央是綠、紫、藍、橙四個鹼基兩兩配對，淡藍虛線氫鍵清楚，兩側是半透明藍灰珠串骨架，右下一條橙色鏈標"Emerging RNA"，四周虛化的彩色分子團，7 個英文標註都拼寫正確。

常見問題：

• 氫鍵數量畫錯：在提示詞裏保留"A–T 兩條、G–C 三條"這類明確數字。
• 標註跑位：每個標註都寫清"什麼顏色、指向哪裏"。
• 科學細節：示例的化學結構是示意圖，正式教材使用前請對照課本檢查環結構。

適合：生物課件、科普公眾號、考研 / 高中生物筆記配圖、PPT 插圖。

Goal: Create a polished 3D scientific educational infographic titled {argument name="headline text" default="DNA Nucleotides"}, showing a close-up view of a DNA double helix with labeled nucleotide bases and molecular structure.

Canvas: Landscape 4:3 composition, bright white laboratory-style background with soft depth-of-field molecular clusters in pale blue, lavender, mint, and purple around the edges. Use a clean, high-resolution textbook/medical visualization style with realistic glossy translucent spheres and rods, soft shadows, and shallow depth of field.

Layout: Center the title at the top in large dark navy bold type, with the subtitle {argument name="subtitle text" default="A close-up view of the DNA double helix"} directly beneath in smaller medium-blue type. Fill the frame with a large twisting DNA double helix running from the left foreground through the center to the right side, with a second orange strand crossing diagonally through the lower right foreground. Keep the central base-pair region open and readable for labels.

Subject details: Render the DNA as a molecular ball-and-stick model combined with translucent bead-like backbone surfaces. The sugar-phosphate backbone should be two twisting chains made of semi-transparent bluish-gray spheres with orange/gold connector rods and small red atoms. In the center, show exactly 4 labeled nucleotide bases: Adenine (A) in green at upper left center, Thymine (T) in purple at upper right center, Guanine (G) in blue at lower left center, and Cytosine (C) in orange at lower right center. Adenine pairs with Thymine across the top using dotted pale blue hydrogen bonds, and Guanine pairs with Cytosine below using three dotted pale blue hydrogen-bond rows. Molecular rings should be flat aromatic ring structures with small colored atom spheres and white hydrogen atoms.

Text content and labels: Include exactly 7 callout labels with thin black pointer lines: “Adenine (A)” in green pointing to the green upper-left base; “Thymine (T)” in purple pointing to the purple upper-right base; “Guanine (G)” in blue pointing to the blue lower-left base; “Cytosine (C)” in orange pointing to the orange lower-right base; “Sugar-phosphate backbone” in black pointing to the right-side helical backbone; “Hydrogen bonds” in black pointing to the dotted bond lines between base pairs; and “Emerging RNA” in orange pointing to the orange strand crossing the lower foreground. Use crisp sans-serif typography and avoid crowding.

Visual style: Hyper-detailed scientific 3D render, glossy translucent molecular beads, realistic refraction, soft bokeh background, professional biology textbook infographic, balanced educational clarity and cinematic depth.

Constraints: Use exactly the 4 nucleotide labels and exactly the 3 structural labels listed above; do not add extra labels, icons, captions, legends, watermarks, or borders. Keep all text sharp and correctly spelled.
