// （esbuild 打包为 dist/v2/loader.js，宿主以 <script src="{EMBED_ORIGIN}/

// 零全局（仅版本标记属性）、无 console、一切错误静默不抛（A11 不破坏宿主）。
|
||
//
|

// v2 与 v1 的宿主侧差异（方案 §2/§7/§8）：

||
// 仅在视口不足时按 min(195,可用宽)/min(280,可用高) 收缩，绝不 transform
|
||
// 缩放；resize 消息不改高度（iframe 内容自适应窗口，窗口不迁就内容）；
|
||
// · 外壳：圆角 12、边框 1px rgba(255,255,255,0.80)（单圈）、阴影
|
||
// 0 4px 16px rgba(15,23,42,0.16)、底色 #10161E（加载/缺口不露宿主内容）；

// · 默认停靠：桌面 right 16 / 手机 right 12，bottom 24 + safe-area-inset；
|
||
// offsetX 仅在 data-* 与后台都未配置时按视口取默认；
|
||
// · 收起把手：白底胶囊 88–104×44、圆角 22、蓝图标 + 12px「照片/Photos」；
|
||
// · 多槽同侧纵排间距 12；可用高度不足时后续槽收起（空间约束≠用户选择）；

// · 窄屏（<480px）默认收起沿用 v1 策略；展开后两端尺寸一致（195×280）。
