Темный редакторский слайд для AI Keynote

A premium dark presentation slide in a minimalist editorial tech style, widescreen 16:9 layout, matte black background with refined off-white typography and subtle gray divider lines. The mood is sleek, cinematic, and high-end, resembling an executive AI product keynote slide. In the top-left corner, two small navigation lines: "UI SCENE · OPEN HARNESS" and below it "DEEP AGENTS" in thin uppercase sans-serif with wide letter-spacing. In the top-right corner, a subtle slide index: "07 / 08". The main headline dominates the upper left in large elegant mixed serif Chinese and English typography: "[开放 harness,开放记忆。]". Below it, a two-line Chinese body paragraph in smaller serif text: "[解决方案不是让模型供应商替你保管状态,而是把 harness、标准和记忆后端都放回开发者手里。]". In the left-middle area, three horizontal feature rows separated by thin gray lines; each row has a bold Chinese label on the left, a short Chinese description in the center, and a small uppercase English keyword right-aligned: Row 1 has "标准", "agents.md / skills 让上下文入口可见。", "OPEN"; Row 2 has "模型", "模型可替换,记忆不应被单一平台绑定。", "AGNOSTIC"; Row 3 has "存储", "Mongo / Postgres / Redis 可作为自有记忆后端。", "OWNED". On the right side, a large embedded software UI mockup inside a soft light-gray rounded rectangular frame with a subtle drop shadow. The dashboard UI mockup is monochrome light beige and gray with three distinct columns: left column has a narrow icon sidebar and a file tree listing "agents.md", "skills", "workflows", "memories", "tools", and a code editor panel at the bottom; center column shows a module titled "模型无关" with 4 selectable model rows, small controls, and 3 lower feature cards; right column shows a module titled "记忆后端" with cards for MongoDB, Postgres, and Redis, plus a lower code snippet panel titled "可迁移"; a top header card inside the mockup reads "开放标准" with tabbed controls. Bottom-left outside the mockup features a tiny caption: "UI 情景图 · 三张同高画面板测试". Bottom-center features a pagination carousel of 8 small dots, the 7th highlighted as a white pill shape and the others as dim gray dots. Bottom-right shows page number "07" and an ultra-subtle presentation metadata footer note. Precise Swiss grid alignment, ample negative space, luxury dark-mode aesthetic.
