<!-- 大图标菜单 -->
<ul class="dropdown-menu dropdown-menu-lg-end show" style="margin: 0px; transform: translate3d(0px, 38.4px, 0px);" data-popper-placement="bottom-end">
    <li><a class="dropdown-item" href="#"><span class="material-symbols-outlined">share</span>&nbsp;Export</a></li>

<!-- 小图标菜单 -->
<ul class="dropdown-menu dropdown-menu-lg-end show" style="inset: 0px 0px auto auto; margin: 0px; transform: translate3d(0px, 38.4px, 0px);" data-popper-placement="bottom-end">

关键修改点 #

• 移除重复嵌套的<style>标签，保证样式结构合法
• 在字体链接中同时引入opsz=24和opsz=40的图标变体，确保两种尺寸资源加载正常
• 规范font-variation-settings参数格式，添加空格和换行提升可读性与解析准确性
• 给第二个菜单的所有图标元素应用material-symbols-outlined-small类，启用小尺寸样式
• 将align-middle整合到样式类中，减少内联重复代码
