Key points

When handling nested border-radius, set the inner radius to equal the outer radius minus the spacing, or use superellipse to achieve the continuous rounded corners seen in iOS.
Control interface colors—avoid using too many. Stick mainly to black, white, and gray, reserving color for content only.
Standardize fonts and sizes, limiting yourself to no more than four font sizes. For Chinese typography, write font-family with Western fonts first, followed by Chinese fonts, and end with sans-serif as fallback.
Refine border and line details by simplifying all borders to 0.5px, avoiding the overused 1px borders.
Have the AI use popular UI component and utility libraries (such as Radix Colors) during development, or cross-check against an AI slop checklist for self-review.

Pitfalls

Poorly handled nested border-radius that makes the interface look cheap
Overusing color, resulting in visual clutter
Using overused font combinations, purple gradients, all-caps subtitles, and 1px thick borders (classic AI slop traits)
Typography issues when AI generates Chinese-language pages

.cursorrules

- Nested border-radius: inner radius = outer radius - spacing
- Use 0.5px borders; avoid 1px thick borders
- Limit to no more than 4 font sizes
- Be restrained with color—favor black, white, and gray; reserve color for content
- Font stack: Western fonts first, Chinese fonts second, sans-serif as final fallback

Copy-ready prompt

Help me optimize the frontend interface design of the current page: 1. Fix nested border-radius by setting inner radius to outer radius minus the spacing, and try using superellipse to create continuous rounded corners; 2. Reduce color usage—primarily stick to black, white, and gray, reserving color only for content; 3. Standardize all borders to a 0.5px hairline; 4. Limit the number of font sizes to no more than four; 5. For Chinese typography, follow the font-family rule of listing Western fonts first, followed by Chinese fonts, and ending with sans-serif as fallback. Use the [input your component library name] component library to elevate the overall interface quality.
