/**
|
|||
|
|
* 家书 FamilyBook · 「新建旅程」浮层（鸿蒙端）
|
|||
|
|
*
|
|||
|
|
* 对应网页版 `templates/trips/form.php`（新建那一路）。
|
|||
|
|
*
|
|||
|
|
* 🔴 为什么单独做这一批：端上原来的「新建旅程」按钮**根本没接 `onTap`**
|
|||
|
|
* （`FbTripsPage` 里 `FbPrimaryButton({ label: '新建旅程', ... })` 没有回调），
|
|||
|
|
* 点了什么都不发生 —— 用户报的"新建旅程没完成"就是这一条。
|
|||
|
|
*
|
|||
|
|
* ⚠️ 表单只放**网页版真有的三项**：
|
|||
|
|
* 标题 / 简介 / 是否公开。**没有起止时间、没有城市** ——
|
|||
|
|
* 服务端 `Trip::create()` 显式忽略它们，城市与时间一律从行程节点**派生**
|
|||
|
|
* （见 `Trip::derived()`）。加个"时间"输入框只会让人以为填了有用。
|
|||
|
|
*
|
|||
|
|
* ⚠️ 题图这一批**不做**：网页版走 `cover` 文件上传 + `cover_crop` 裁剪，
|
|||
|
|
* 而服务端目前只有观影的 `/movies/<id>/poster` 上传槽位，没有旅程的。
|
|||
|
|
* ⇒ 新建时先不传图；列表卡仍会显示已有数据的题图。
|
|||
|
|
* （补上传端点时要与网页版 `ImageSlot` 的 `cover` 槽位比例 16:9 一致，
|
|||
|
|
* 否则宽高比会和网页端不一样 —— 那条在 app.css 里有专门的断言比对。）
