/* =========================================================
   Component: Blog Sign-up Box (blog-sign-box)
   ---------------------------------------------------------
   - 抽出元: yoyipapa-web-bkc
     packages/next/src/app/[locale]/(blog)/blog/[id]/BlogSignBox.tsx
     packages/next/src/app/[locale]/(blog)/blog/[id]/BlogContent.tsx
   - 用途: 博客详情页右侧 sticky 手机号/邮箱注册版块
   - 依赖 JS: js/blog-sign-box.js (手机号校验 + check-user API + 埋点)
    - 使用方式(桌面右侧 sticky 侧栏):
        1) <link rel="stylesheet" href="css/blog-sign-box.css">
        2) <script src="js/blog-sign-box.js"></script>  (建议放 body 末尾)
        3) 放置挂载点: <div class="blog-sign-sticky" data-bsb-mount></div>
        JS 会从缓存模板生成 .blog-sign-box，调用页不再复制组件内部结构。
        移动端直接使用 <div data-bsb-mount></div> 即可自动全宽。
   - 此组件已针对 Konkatsu 站点设计，可使用 CSS 自定义变量覆盖颜色：
     --bsb-title-color:    标题文字颜色   (默认 #da1c1c)
     --bsb-subtitle-color: 副标题文字颜色 (默认 #da1c1c)
     --bsb-gold-gradient:  金色渐变背景   (默认原 React gradient)
   - 组件输入框使用 Konkatsu 站点的 --color-border, --radius-md, --font-jp 变量，
     以保持与站点其余表单的视觉一致性。
