/*!
 * 评论区样式
 * Yongquan Yang <yangyq.net>
 *
 * ── 为什么整块重写，而不是在旧样式上改 ──────────────────────
 * 旧样式的骨架是「头像 float:left + 右侧 margin-left 挤出来」，
 * 这个结构在三个地方会坏：
 *   · 长昵称/长网址会把头部撑破（float 不定宽容器里没有约束）；
 *   · 嵌套回复靠 .children { padding-left:0 } 实现，等于**没有缩进**，
 *     三层以后完全看不出谁回谁；
 *   · 头像 50px 写死在 img 上，但没有 flex 居中，头像和第一行文字
 *     基线对不齐（看起来"文字比头像低一点"）。
 *
 * 所以改用 flex 两列布局：头像固定宽、主体 flex:1，
 * 并把嵌套缩进做成明确的层级视觉（左侧引导线）。

3. 单条评论

/* 单条评论的布局：头像列 + 主体列
 *
 * ⚠️ 这里**必须是 grid，不能是 flex**。
 * 原因：wp_list_comments 输出的是
 *     <li class="yang-comment">
 *         <div class="yang-comment-avatar">…</div>
 *         <div class="yang-comment-main">…</div>
 *         <ol class="yang-children">…子评论…</ol>   ← 也是 li 的直接子元素
 *     </li>
 * 若 li 用 display:flex，那个 <ol> 就成了**第三个 flex 项**，
 * 被排到主体右边的同一行里 —— 表现为"子评论跑到父评论右侧"、
 * 父评论正文被挤成一条、页面出现横向溢出。这是真实渲染量出来的，
 * 光看代码几乎想不到（flex 项的位置不体现在 li 自己的属性上）。
 *
 * grid 用两列：第 1 列 auto（由头像定宽），第 2 列 minmax(0,1fr)
 * （minmax 的下界 0 是关键，否则长英文/长 URL 会把列撑宽）。
 * 子评论用 grid-column: 1 / -1 独占下一整行。 */
