   ISABER 正文对比度防线 — 白卡深字（v5 · 定稿）
   ──────────────────────────────────────────────────────────────────────
   症状：正文白卡里的文字是浅色（#C7D2DF / #ffffff）压白底 → 对比度 1.00，完全隐形。
   根因：主题 assets/blog-layout.css 为**深色页面**服务（实测页面底色 #0A1628），
        把 .entry-content 的 p/h3/li/strong 一律 !important 染浅 —— 它不知道正文里有白卡。
        级联实测：body.single-post .entry-content h3 = (0,2,2)  ← 赢
                  .sbx .svg-wrap h3                = (0,2,1)  ← 输
        所以套件自己写的深字规则会被主题压掉。

   ⛔ 两条设计红线（v1~v4 翻车教训，勿犯）：
     ① **绝不动全局正文色**。页面底色是深色，正文本来就该是浅字。
        v2 用 `color:inherit` 把正文带成深字 → 深底深字全站 1.01，比原病更糟。
     ② **只给"经全站矩阵验证恒为浅底"的容器补深字**。
        v3/v4 凭印象加了 `.cbar-wrap`、`.viz-section` → 前者在深底上、后者时浅时深，
        共在 27 个页面制造出 200+ 处新的深底深字。

   ✅ 安全依据：scan_container_matrix.py 扫遍 **97 页全部类名容器**，
      下面列出的 7 个容器**每一页都是浅底**（0 次深底），故可一刀切。

   特异性：`body.single-post .entry-content .容器 标签` = (0,3,2) > 主题 (0,2,2)；
          双方都 !important 时由特异性取胜，与源顺序无关。

   矩阵实测（浅底节点数 / 出现页数）：
     .wtab-wrap    25/11   .svg-wrap 13/11   .isaber-card 2/2
     .ic-thumb      2/2    .lfs-bars  2/2    .lfs-spec-card 1/1   .lfs-card 1/1
   ⛔ 不含 td —— `.sbx .wtab td` 本来就是深字，无需覆盖。
   ⛔ 不含 th —— 表头是深底 #132A4A，必须保持浅字（见 ③）。
   ⛔ 不含 .viz-section —— 时浅时深（浅11/深7/透明22），**不可按类名修**。
   ⛔ 不含 .cbar-wrap —— 自身无背景，落在深底上，文字应保持浅色。 */
