The project uses `@tailwindcss/postcss` (v4) and imports Tailwind via `@import tailwindcss` in globals.css, but no PostCSS configuration file existed to register the plugin. Without it, Next.js never processes the Tailwind directives and all utility classes are absent in production builds — resulting in completely unstyled output. Fixes OpenKnots#84

Summary
postcss.config.mjswith@tailwindcss/postcssplugin registrationRoot Cause
The project uses Tailwind CSS v4 (
@tailwindcss/postcssin devDependencies) and imports it via@import "tailwindcss"inapp/globals.css. However, no PostCSS configuration file existed to register the plugin with Next.js.Without this file, the
@import "tailwindcss"directive is never processed — all Tailwind utility classes (flex,p-4,text-sm, etc.) are absent from the compiled CSS, resulting in completely unstyled HTML output as shown in #84.Why this wasn't caught locally
pnpm devwith Turbopack may have a different CSS pipeline behavior that masks the issue. Production builds (pnpm build) and Vercel deployments rely on PostCSS processing, which requires the config file.Test plan
