    /* ═══════════════ 暖色纸 · 文件图标品类分色（2026-10-09 用户定稿"方案B"）═══════════════
       背景：暖色纸下图标三色原先全走 --primary(#2c2c2c 冷墨灰) 系 → 整片发灰。
       做法：**只改文件图标**，不动主题 --primary（按钮/表头/标签等还在用它）。
         ① 纸张轮廓 → 中性暖灰（--ifb-paper / --ifb-paper-line，见 lingdu-files-thumbs.js 的 `_ifbSheet`）；
         ② 图形主色 → 品类色（在该 svg **局部**把 --primary 重定向到 --ifb-ink）；
         ③ 图形辅色 → --accent-2 重定向到 --ifb-ink-2。
       只对 `html[data-theme="shuimo"]` 生效；其它主题无此规则 → 保持原单色，行为不变。
       品类 class（ifb-t-<品类>）由 lingdu-files-thumbs.js 挂，取值范围同 IFCON_EXTS：
       sheet / doc / text / image / video / audio / cad / ppt / code / archive / file / folder。 */

       适用位置（用户点名）：
         · 钢筋物资 → 统计汇总 的**行6 / 行7**（"进场−预算 / 进场−翻样"两个差值行）；
         · 预算翻样 9+3 个表 的**行8**（"进场 − 预算"）。
