The first production build after the Bun migration failed in Next.js 16.3 with
__turbopack_context__.a is not a functionwhile loading PostCSS. This matches the upstream cold-build runtime race: vercel/next.js#96619.Rename the existing CommonJS config to
postcss.config.cjsto avoid its asynchronous.jsloader. The configuration contents, Tailwind/Autoprefixer plugins, dependencies, and build commands remain identical.Validation: fresh Bun 1.4.0 frozen install; uncached production Turbopack build passed all 6 tasks; Next config discovery and plugin parity checked; generated failing wrapper absent; scoped Biome passed. The Vercel preview also passed all 6 build tasks with 0 Turbo cache hits and deployed successfully: https://vercel.com/mc-ilroy/cap-web/HuH92gBL33AX8CaCTcgZrFvbN1Jw.
