/* ================= 首页操作引导（2026-10-12） =================
|
||||
用户：「给首页加上引导操作步骤」。第一次进首页时，一步一步高亮讲 5 个地方：
|
||||
① 头图孕周 ② 孕育工具 ③ 此刻 ④「记一下」圆钮 ⑤「我的」
|
||||
· 只走一次：看完或点「跳过」都记 localStorage 'mmbox.coach.v1'，以后不再出（同 onboarding-once-rule）。
|
||||
· 调试 / 给人看：URL 带 ?coach=1 每次都出。
|
||||
· 不抢别的弹层：授权、欢迎礼、孕期档案、记一下面板、详情页等开着时不计时，
|
||||
全部关掉、首页安静 1.5 秒后才开始；引导进行中别的弹层冒出来 → 暂时收起，等它关了从当前步接着讲。
|
||||
· 某一步的目标不在页面上（如「此刻」接口没数据整块隐藏）→ 自动跳过这一步，不留空框。
|
||||
· 遮罩挂在 #phone 里（跟页面同一个坐标系），z-index 高于所有弹层；滚动交给首页 .screen，引导时锁住。 */
