/* 星空页 · 妈妈们的留言（2026-11-07 用户：广场点「孕妈悄悄话」直接进星空页，留言自带在「说一句悄悄话」下面，
   样式跟星空搭，不要白底）。
   · 版式：#wcm 盖满星空页、自己滚动、本身不接点击；上面一段透明垫高（点得到星星），下面是留言面板，
     把原来的 .whp-bar（说一句悄悄话）挪进面板顶上，往上滑留言就盖上来。
   · 数据：广场置顶笔记 wh-<话题 from> 的评论 = cm.json 模拟（AGENTS.md 12c，不得挂星）+ /plaza/comments 已审核通过的真实评论
     + 我自己发的（含审核中）。进星空页才拉 cm.json（600K+，gzip 后小很多；版本号跟广场 index.html 引的一致，共用缓存）。
   · 赞只记本机 mmbox.whcm.v1（服务端计数是悄悄话第 2 步）。 */
