/* 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；上面一段透明垫高，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）。
   · 11-07 第 2 步：真实留言的赞走服务端（POST /plaza/comment/like，每人每条一次、不能赞自己），赞够 starLikes（后台可改，先 3）
     自动挂到星空，挂上的标「已挂上星星」；模拟留言的赞只记本机 mmbox.whcm.v1（模拟的永远不挂星）。
     最热 / 最新 / 同孕周 三种看法；星空页「说一句」发的话也进这里（window.MBWhCm.post，app.js 调），先审后发。 */
