How to remove unused Tailwindcss v4 classes when building a library with Vite?

I'm building a Vue 3 component library using Vite and Tailwind CSS, but I want to ensure that the final build only includes the Tailwind classes that are actually used in my components.

Right now, the entire Tailwind CSS framework is being bundled, which significantly increases the file size.

When I build the package, the entire Tailwind CSS framework is included, even though I only use a small set of classes.

I want tree-shaking/purging in the config so that only the used Tailwind classes are included in the final dist/ output

My file structure:

import { resolve } from 'node:path'
import tailwindcss from '@tailwindcss/vite'
import Vue from '@vitejs/plugin-vue'
import { defineConfig } from 'vite'
import Dts from 'vite-plugin-dts'

export default defineConfig({
  plugins: [
    Vue(),
    Dts({
      tsconfigPath: './tsconfig.json',
    }),
    tailwindcss(),
  ],

  build: {
    target: 'es2015',
    minify: false,
    copyPublicDir: false,
    outDir: 'dist/',
    lib: {
      name: '@hetari/image-editor-vue',
      entry: {
        index: resolve(__dirname, 'src/index.ts'),
      },
      formats: ['es'],
    },
    rollupOptions: {
      external: ['vue', 'tailwindcss'],
      output: {
        exports: 'named',
        globals: {
          vue: 'Vue',
          tailwindcss: 'tailwindcss',
          assetFileNames: 'style.css',
        },
      },
    },
  },
})

How can I configure Tailwind CSS or Vite to remove unused styles in my library?
