Summary

Removes the autoprefixer PostCSS plugin and its devDependency, since Tailwind CSS v4 uses Lightning CSS internally which handles vendor prefixing natively.

Why

Tailwind CSS v4 processes CSS through Lightning CSS, which automatically handles vendor prefixing. Having autoprefixer as a separate PostCSS plugin is redundant — all prefixing is already handled by @tailwindcss/postcss.

Changes

  • postcss.config.js: Removed autoprefixer import and plugin entry
  • package.json: Removed autoprefixer from devDependencies

Test Plan

  • All 52 existing tests pass unchanged
  • Production build completes successfully (no CSS processing errors)
  • No behavior change — Lightning CSS within @tailwindcss/postcss handles all vendor prefixing

Tailwind CSS v4 uses Lightning CSS internally, which handles vendor
prefixing natively. The separate autoprefixer PostCSS plugin was
redundant, as all prefixing is already handled by @tailwindcss/postcss.

- Removed autoprefixer from postcss.config.js
- Removed autoprefixer from devDependencies in package.json
