/* ============================================================
   全站底部 · 唯一实现（2026-11-07：footer-2 设计稿，格式原样照搬）
   结构：CTA 横幅 + 标志/版权/二维码同排 + 单行免责 + 链接条 + 两段声明
   主题：白天默认；夜晚走 html[data-theme="dark"] 与 body.night 双写
         （与顶栏 nav-site.css 同一套令牌）
   注意：类名全部 lwxf- 前缀 + .footer-wrap 作用域，
         避免与站内 .cta（16-home.css 内容卡）等冲突。
   版权行图标必须 inline-block：站点全局 img 规则会把它拆成两排。
