Cinematic Thread Archive Search Poster

Goal: Create a cinematic vertical tech poster about searching historical conversation threads by content and branch name in a developer app.

Canvas: Vertical 2:3 composition, dark premium editorial style, deep navy-black background with subtle star-like dust and a warm golden beam of light entering from the upper right.

Main text: At the top center, large bold Chinese headline [headline text]. Below it, centered smaller gold subtitle [app version]. Add a tiny decorative divider line with a small diamond under the subtitle.

Main subject: In the lower half, show an old dark metal archive filing cabinet at a three-quarter angle, with one drawer pulled open toward the viewer. The drawer front has a brass label plate reading “THREAD ARCHIVE” and a curved brass handle. The cabinet surface should feel heavy, matte, slightly worn, and realistic, with shallow depth of field.

Drawer contents: Inside the open drawer, show exactly 4 prominent stacked paper thread cards, each like an archival index card with rounded corners, warm ivory paper, and a small dark chat-bubble icon at the left. The visible card texts are: 1) “导出功能支持哪些格式?” with branch tag “feature/export-csv”, 2) “新版 API 兼容性讨论” with branch tag “refactor/api-v2”, 3) “用户登录流程的边界情况” with branch tag “fix/login-edge”, 4) front glowing card “如何优化加载性能?” with branch tag [featured branch tag]. The front card should glow brightest, as if it has been found by search.

Floating UI elements: Add exactly 2 floating search-result elements to the right of the drawer: one glowing branch label reading “feature/perf-opt” connected by a dotted golden path from the front card, and one small outlined chat bubble containing three dots. Add exactly 4 branch tags attached to cards in the drawer, one per card, styled as thin rounded rectangles with a branch icon.

Lighting and mood: Use a warm golden particle trail and dust motes around the highlighted card and floating branch label, contrasting with the cool dark cabinet. Make the scene atmospheric, elegant, high-end, and slightly magical, like an archival search feature visualized as light finding the correct thread.

Visual style: Realistic 3D illustration mixed with refined product-marketing poster design, cinematic lighting, soft bloom, shallow depth of field, crisp typography, subtle grain, no people, no extra logos, no watermark. Keep all text legible and avoid adding additional labels beyond the specified headline, subtitle, card texts, branch tags, and drawer label.
