/* ---------- Buttons ----------
   这是给「文章正文、评论表单」等原生内容里的按钮准备的默认外观。

   选择器用 :where() 包起来，把特异性降为 0。原因：

   裸写 button:hover 的特异性是 (0,1,1)，而各 Elementor 小部件的按钮
   样式通常是 .qxx-btn（0,1,0）。CSS 的特异性是按属性逐个比较的，
   于是只要小部件的 :hover 规则漏写了某个属性（最常见是 background），
   该属性就会落到这条全局规则上 —— 表现为「悬停时按钮突然变成深绿色」。

   .qnp-tab 就踩过这个坑：它的 :hover 只声明了 color 和 border-color，
   background 被 button:hover 的 #245840 接管。

   :where() 内部的选择器不贡献特异性，因此这一组变成「谁都能覆盖」的
   基础层，小部件不必再逐个防御性补齐属性。
   注意 :where() 需要较新的浏览器（Chrome 88+ / Safari 14+ / Firefox 78+）；
   更老的浏览器会整条丢弃这组规则，那时按钮回落到浏览器默认外观 ——
   可用性不受影响。 */
