/* ui/search.c — 搜索页（ACT_SEARCH，顶栏搜索按钮进入）。
|
||
*
|
||
* 独立页面：搜索输入框（SDK TextField，接 IME §5.1，仅英文/数字）+ 红色「搜索」按钮 +
|
||
* 结果列表（点击可播，复用 g_st.songs[] 起点：播放/上下一首均对结果集生效）。
|
||
* 搜索结果网络走后台 worker（search_worker），UI 不卡。
|
||
*
|
||
* 风控纪律（用户指定）：**搜索请求只在用户确认时发**——用户点「搜索」按钮才发起 cloudsearch，
|
||
* 进入页面不自动搜索；IME 输入仅本地编辑，不逐键发请求。
