全局样式建议放入 src/styles/，并在 main.ts 中引入：
ts
复制编辑
import '@/styles/reset.css'
import '@/styles/theme.css'
推荐模块化结构：
pgsql
复制编辑
styles/
├── reset.css 初始化样式
├── variables.css 颜色、字体等变量
├── theme-dark.css 暗色主题
├── theme-light.css 明亮主题
Vue3 中也可以使用 CSS 变量切换主题：
css
复制编辑
:root {
--main-color: #42b983;
}
[data-theme='dark'] {
--main-color: #121212;
}
配合 document.documentElement.setAttribute('data-theme', 'dark') 实现动态主题。
