Follows docs/tailwind-v4-migration.md: installs @tailwindcss/postcss and points Angular's PostCSS pipeline at it via .postcssrc.json, swaps the @tailwind base/components/utilities directives in styles.css for @import "tailwindcss", and bridges the existing tailwind.config.js (darkMode: "class", content globs) via @config so nothing else needs to change. Drops autoprefixer, which v4 now handles internally. Verified with a production build, the full test suite, and a visual check of the dev server in both light and dark mode.
