/**
 * 友链自助申请弹窗
 *
 * 为什么独立成模块（而不是留在 layouts/page/comment.html 的内联 <script>）：
 * 那段脚本写在 #pjax-container 外面，PJAX 只换容器内容、不会重新执行它 ——
 * 用户从首页 PJAX 进留言页时 window.flApplyOpenModal 根本没定义，
 * 「申请友链」卡片点了没反应；直接刷新（整页加载）才正常。抽到
 * page-only bundle 里随 PJAX 加载，两种进入方式行为一致。
 *
 * 幂等性：弹窗节点挂 document.body（跨 PJAX 存活），buildModal 二次调用直接复用；
 * 事件监听只在首次构建时挂，不会重复注册。
