/* ==========================================================================
   视频去水印 · 独立样式表（千纸鹤情感网 2026-10-10 生成）
   本文件自包含：全站基础层 + 本页专属样式，不依赖任何其他 CSS 文件。

   为什么每页独立：原先所有页面共用 /tool.css，改任一页的基础样式会同时
   影响另外 6 页 —— 2026-10-10 mp3jj「跑偏」事故即由此产生。

   维护方式：
     · 只调本页外观 → 直接改本文件下半部分「本页专属样式」段
     · 要改所有页面的基础层（如顶栏、页脚）→ 改 tools/build/tool.css
       后重新运行 tools/build_page_css.py 一键重生成全部

   千纸鹤情感网 2026-10-09 全面升级
   - PC 端宽大清晰（内容区最大 1320px / 更大的字号与留白）
   - 手机端自适应（单列 / 触控友好 / 安全区适配）
   - 统一页脚（关于本站 / 联系我们 / 免责声明 / 隐私政策 / ICP 备案）
   - 微信内置浏览器提示条
   注意：类名一律带站点前缀（.site-* / .home-* / .wb-*），
     避免与各工具页自身的 .wrap / .card / .brand 等类名冲突
