// Vue builds with vite, whose CSS pass auto-discovers the nearest PostCSS
// config. React instead runs the standalone `tailwindcss` CLI in a separate
// `build:css` step because tsup does not process CSS — so the equivalent for
// Vue is to wire Tailwind into vite's existing PostCSS pass here rather than
// add a separate step (which would clobber the SFC <style> CSS vite emits).
//
// The tailwind config path is absolute so it resolves regardless of the cwd
// the build runs from (see issue #340).
