Minimal AI Lock-In Comparison Slide

A minimalist editorial presentation slide in 16:9 format with a warm light-gray paper background, lots of negative space, refined Swiss-style grid layout, and high-end PPT/keynote design aesthetics. The slide is a comparison page about lock-in, using elegant Chinese typography mixed with tiny English navigation text. At the top left, place two small uppercase English breadcrumb lines: “COMPARISON · LOCK-IN” and below it “CLOSED VS OPEN”, in a thin sans-serif with wide tracking. At the top right, place the page indicator “04 / 08”. Center-left across the upper half, add a very large bold black Chinese headline: “真正的锁定，不是模型，是记忆。” On the left half below the headline, create a three-row comparison list separated by thin horizontal gray rules. Row 1 has the bold Chinese label “轻度风险” on the left, with the explanatory sentence “状态存在服务端，换模型后无法恢复线程。” to its right, and a tiny uppercase English keyword aligned far right: “STATE”. Row 2 has the bold label “中度风险”, with the sentence “闭源 harness 的记忆形态不可见,难以迁移。” and the far-right keyword “SHAPE”. Row 3 has the bold label “最高风险”, with the sentence “整个 harness 和长期记忆都在 API 后面。” and the far-right keyword “LOCK-IN”. On the right side of the slide, place a small inset comparison diagram card with a white background and subtle border, containing 2 side-by-side system architecture panels. The left panel represents a closed system in dark gray and muted red accents; the right panel represents an open system in deep blue accents. Each panel should have 5 small top icon tabs, a central highlighted harness block, several stacked rounded rectangular modules below, and a bottom row of 4 small capability icons with short Chinese labels. Keep the inset detailed but small, so it reads as a supporting visual rather than the main focus. At the bottom left, add tiny light-gray Chinese footer text: “布局测试 · 顶部标题 + 下方两段式内容”. At the bottom right, place a small page number “04”. Centered near the bottom edge, add a carousel indicator with exactly 7 small dots, where the 4th dot is a short dark rounded pill indicating the active slide and the other 6 dots are pale gray circles. Also add tiny faint navigation hints at the lower right edge reading “← → 翻页   ESC 关闭”. Use crisp vector text rendering, understated contrast, elegant spacing, and a calm premium infographic style suitable for a business presentation about AI platform comparison and API memory lock-in.
