   v1.5.0-beta.2 — 全站排版与样式对齐（design-system alignment）
   ------------------------------------------------------------
   审计发现的三类"没对齐"：
     a) .page-header 此前**只在媒体查询里出现**，没有任何基础规则 →
        页头节奏全靠各页 markup 里的 mb-* 工具类接力，页与页不一致；
     b) 卡片标题的上下间距由浏览器默认 margin 决定（h1 0.67em / h3 1em），
        再被各页零散的 mb-* 覆盖 → 同一种标题在不同页面间距不同；
     c) 若干语义类被 markup 使用但从未定义（.pv-* / .setting-* / .stats-grid
        / .rd-image-preview），靠工具类兜底，语义形同注释。
   本节把这三件事收成单一来源。**只做对齐，不换风格**。
   ============================================================ */

/* a) 页头：统一底部节奏与标题间距。

.page-header > div { min-width: 0; }

/* b) 卡片：标题字号与首末间距统一（只作用于直接子元素，
      避免影响 .empty-state 等嵌套结构的内部标题） */
.card > h1, .card > h2, .card > h3 {

.card > :first-child { margin-top: 0; }
.card > :last-child { margin-bottom: 0; }

/* c) 统计卡网格：四张卡之间 16px 比 24px 更聚拢（24px 会显得彼此无关） */
.stats-grid { gap: 16px; }

/* d) 存储实例字段（.pv-*）：此前无任何定义。

   首页 hero 统计：单一来源 + 行盒统一（2026-09-14 对齐修复）
   ------------------------------------------------------------
   修复前，这一个视觉位置散着 10 条规则，且是**两套等特异度规则互相覆盖**：
     · `.hero .stats .stat-value`（原 1285 行）实际只赢到了 line-height
     · `.hero .stat .num`（原 1373 行，文件更靠后）赢到了 font-size / font-weight
   —— 同一个数字被两条规则各管一半，"改哪里才生效"无从判断；
   而**第三个数字的 markup 只挂了 `num`、没挂 `stat-value`**，于是拿不到
   line-height：它的行盒是 2.2rem × 1.6（继承 body）≈ 3.52rem，另两个是
   2.2rem × 1.15 ≈ 2.53rem，**高出约 16px** → 它的标签被推低 16px，
   数字本身也在更高的行盒里居中而显得偏低偏大（线上截图即此现象）。
   顺带发现：移动端的 1.6 / 1.4rem 收缩（原 555 / 561 行）同样被 1373 行覆盖，
   **从未生效** —— 这里按注释里记的原始意图（v1.2.0「stack stats, shrink」）恢复。

   现在收敛为**一条**规则，并把 line-height 显式写死：
   三个数字的**行盒等高 ⇒ 标签必然共线**。这是结构上的保证，
   不依赖"三项内容恰好同高"这种巧合。
