Judgement

What it is

Building block

What it does

Lets you write styles in TypeScript files with locally scoped class names and typed CSS variables, then generates static CSS at build time with no runtime.

Adopt it when

You want type-safe, themeable styles without CSS-in-JS runtime cost, for example in a design system.

Watch out

It needs a bundler plugin for Vite, webpack, esbuild or Next.js, and styles must live in separate .css.ts files.
