Tailwind vs CSS-in-JS, which does Claude Code prefer?

Whichever your codebase uses. We don’t force a stack. Claude Code reads your existing patterns, if your repo has tailwind.config.js with custom theme keys, it generates Tailwind utility classes. If it has styled-components with a theme provider, it writes styled blocks against your theme tokens. If it has CSS Modules with BEM, it writes .Component_root__xyz classes. The token pipeline (Figma → theme) adapts: Tailwind config keys, CSS variables, Style Dictionary platforms, or theme-provider object, same Figma source, different output.
