Dark-themed AI product presentation Slides

A high-end dark presentation slide with a minimalist editorial tech style, 16:9 widescreen layout, matte black background, refined gray-white typography, and subtle gray divider lines. The overall mood is sleek, cinematic, and high-end, similar to a product launch or a design-forward AI startup presentation. In the upper left, place two lines of small navigation text: “UI SCENE · OPEN HARNESS,” below it “DEEP AGENTS,” using a thin uppercase sans-serif with wide letter spacing. In the upper right, add a small page indicator showing “07 / 08.” The main title occupies the upper left, using elegant large serif mixed Chinese and English typography: . Below it, add a 2-line Chinese body text using a smaller serif font: . In the left middle area, create 3 rows of horizontal feature rows separated by thin gray lines, each row with a bold Chinese label on the left, a short Chinese description in the middle, and a tiny uppercase English keyword aligned on the right. Row 1 label: “标准,” description: “agents.md / skills 让上下文入口可见。”, keyword: “OPEN.” Row 2 label: “模型,” description: “模型可替换,记忆不应被单一平台绑定。”, keyword: “AGNOSTIC.” Row 3 label: “存储,” description: “Mongo / Postgres / Redis 可作为自有记忆后端。”, keyword: “OWNED.” On the right, place a large embedded UI mockup inside a light gray rounded rectangle frame with a subtle shadow, similar to a screenshot of a product project dashboard. The mockup should be monochrome light beige and gray, rigorously structured, divided into 3 main columns. Left column: a narrow vertical icon sidebar, plus a panel listing items/files such as “agents.md,” “skills,” “workflows,” “memories,” “tools,” and a code editor block at the bottom. Middle column: a section titled “模型无关,” containing 4 rows of selectable models and small controls, with 3 feature cards at the bottom. Right column: a section titled “记忆后端,” containing 3 database cards for MongoDB, Postgres, and Redis, and at the bottom a panel titled “可迁移,” showing a code snippet. Inside the mockup, include another top card titled “开放标准,” with tab-like controls. Outside the mockup, in the lower left, add a line of tiny Chinese and English caption text: “UI 情景图 · 三张同高画面板测试.” At the bottom center, include a carousel indicator made of 8 small dots, with the 7th dot highlighted as a short white capsule shape and the rest as dark gray circles. In the lower right, place a small page number “07.” Additionally, near the lower right edge, add a faint tiny footer note (Chinese and English), very subtle, such as a presentation metadata line. Use precise grid alignment, ample whitespace, understated luxury, Swiss-style composition, and a refined YouMind AI product keynote aesthetic.
