/* ★★ wpautop 铁律（这条踩过坑，改之前先读）：
   wpautop 会「在每个块级标签前插一个换行」，然后「把不以块级标签开头的行包进 <p>」。
   所以整张卡片必须满足两条：
     ① 这一行的开头必须是块级标签 —— 由外面那层 <p class="wmx-tcell"> 提供
        （<a> 不在 wpautop 的块级白名单里，直接当行首一定会被包碎）
     ② <a> 里面只能放 <span> —— 一旦出现 <div>/<p>，wpautop 会在它们前面插换行，
        把这一行切碎，</p> 和 <p> 会插错位置，整个 <a> 就被提前闭合，
        卡片标题会掉到链接外面去（实测踩过）。
   所以这里用 span + display:block 来排版。 */
