🧹 Nitpick comments (2)

package.json (2)

24-24: autoprefixer is redundant in Tailwind v4.

Tailwind v4's built-in Lightning CSS engine handles vendor prefixing automatically. As per the Tailwind v4 docs, there is "no need for separate PostCSS plugins like autoprefixer." Additionally, with postcss.config.js removed, autoprefixer isn't wired into the build pipeline regardless.

🧹 Proposed removal

-    "autoprefixer": "^10.4.24",

18-18: @tailwindcss/postcss is redundant with the @tailwindcss/vite integration path.

@tailwindcss/postcss is the PostCSS-based integration; @tailwindcss/vite (wired in vite.config.ts) is the Vite-native integration. Since postcss.config.js was removed in this PR, @tailwindcss/postcss is never loaded and adds unnecessary maintenance overhead.
