当我在 svelte kit tailwind 项目中使用 Tailwind v4 运行build脚本时，它会添加每一种 tailwind 颜色。我只使用一种 tailwind 颜色，所以我想删除它们。
我花了很多时间在网上搜索并询问 LLM，但没有人能回答无需配置的 tailwind v4 的问题。
这是我的app.css
@import 'tailwindcss';
@theme {
--color-brand-red: #f00;
}
@utility container {
padding-inline: 1rem;
margin-inline: auto;
}
这是我的 package.json：
"scripts": {
"dev": "vite dev",
"build": "vite build",
"preview": "vite preview",
"prepare": "svelte-kit sync || echo ''",
"check": "svelte-kit sync && svelte-check --tsconfig ./tsconfig.json",
"check:watch": "svelte-kit sync && svelte-check --tsconfig ./tsconfig.json --watch",
"format": "prettier --write .",
"lint": "prettier --check . && eslint ."
},
"devDependencies": {
"@eslint/compat": "^1.2.5",
"@eslint/js": "^9.18.0",
"@sveltejs/adapter-auto": "^4.0.0",

然而当我运行时pnpm build我得到一个包含以下内容的 css 文件：

等等。这个文件有 28kb，我使用的独特的顺风类很少。
我搜索了他们的官方文档，似乎只有针对 v2 的文档。有没有办法编辑我的文档app.css以删除所有未使用的颜色？谢谢。
