SolidJS Reactive Framework

SolidJS distilled the best parts of React's component model — JSX, unidirectional data flow, composable primitives — and rebuilt everything underneath with fine-grained signals that update the DOM directly, no virtual DOM diffing required. The result benchmarks alongside vanilla JavaScript while reading like the component code developers already know.

This design system captures the solidjs.com 2024 identity: deep indigo-blue pages that feel like staring into a well-engineered codebase at 2 a.m., solid-cyan accents tracing the spiral-S logo, and typography that treats JSX code samples as first-class visual content rather than afterthought.

SolidJS 把 React 最好的部分——JSX、单向数据流、可组合原语——留了下来，底层全部用细粒度信号重写，直接更新 DOM，不再需要虚拟 DOM 差异比较。性能跑分常年排在框架前三，代码写起来却和开发者已经熟悉的组件写法几乎一样。

这套设计系统还原了 solidjs.com 2024 的品牌气质：深靛蓝页面像凌晨两点沉浸在精心工程化的代码库里，固态青色描出螺旋-S 标志的弧线，排版把 JSX 代码当作视觉主角而非陪衬。
