/**
 * Export dialogs (`e` in the sessions pane, what pi's `/export` does): the
 * format menu and the output-path prompt.

 *   ┌─ Export as ─────────────────────────── FilmRecall ─┐
 *   │ › HTML   whole tree, opens in a browser             │
 *   │   JSONL  active branch, can be imported again        │
 *   └──────────────────────────────────────────────────────┘

 *
 * Only wording for a ./select-dialog.ts and an ./input-dialog.ts preset, like
 * ./restore-dialog.ts. The path is pre-filled with pi's default (the actions
 * layer resolves it); a directory gets the default file name inside it, and an
 * existing file is confirmed (./confirm-dialog.ts) before it is overwritten.
 *
 * 导出只是两个通用弹窗的预设：先选格式（SelectDialog），再输入输出路径（InputDialog，
 * 预填 pi 的默认路径，Esc 退回格式菜单）。目标文件已存在时再弹确认框。
