Launches, search & content, referrals, promotions- 图片都压糊了,为什么还是传不上? 今天测了3个“压缩成功”的文件,对照一组明确的接收要求,3个都不合格。 坑不只在体积,还在格式、像素和“200KB”到底怎么算。 把实测结果和4步排查流程写成了一篇,遇到上传报错时可以直接对照。 https://x.com/i/article/2116035498586300416

# Design Brief: Minimal Monochrome
Monochrome palette with a single accent color, hairline dividers, and generous whitespace.
## Design Tokens
```css
:root {
--background: #0a0a0a;
--surface: #111111;
--foreground: #f5f5f5;
--muted-foreground: #858585;
--accent: #ffffff;
--radius: 16px;
--font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #0A0A0A (~52%) · Surface #111111 (~36%) · Text #F5F5F5 (~5%) · Muted Text #858585 (~6%) · Accent #FFFFFF (~1%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
## Layout & Conversion Structure
- Hero layout: Full-Bleed Canvas / Video / 3D
- Navigation: Full-Width Top Bar
- Theme & density: Dark · Dense
- Border radius & elevation: Large Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Pure Typography & Geometry
- Conversion CTA: Download App / Install Extension · Trust bar uses User Count, Rating, or Key Metrics
- Headline hook: Category Positioning Anchor
- Hero components: Metrics Strip
- Spatial layout notes: Full-Bleed Canvas / Video / 3D hero structure paired with download app / install extension CTA and user count, rating, or key metrics.
- Visual summary: Minimal Monochrome (Dark canvas, dense density) featuring full-bleed canvas / video / 3d layout and pure typography & geometry visuals.
## Avoid
- Multi-stop neon gradients
- Heavy drop shadows
- More than one competing accent color
Implement the UI following the design tokens and layout specifications above: use only these color variables, and reserve the accent color strictly for primary actions and active states. Adopt only this visual style—never copy any reference product’s brand name, logo, copy, or imagery.
