Module file_picker 

File-picker dialog widget — used by the FileChooser xdg-portal backend and any “open / save file from app menu” flow. Self-contained: it draws and hit-tests itself, and the host just positions it as a modal overlay and drains FilePicker::take_outcome.

Top to bottom: title + breadcrumb + up button, a scrollable list of FilePickerEntrys (directory click navigates in file modes and selects in directory mode; double-click navigates; Ctrl/Shift multi-select when enabled), a filename field in Save mode, an optional filter chip, and Cancel/Open(Save) buttons. Keyboard: Up/Down move the selection, Enter opens/enters, Backspace goes to the parent, Escape cancels; printable keys type-ahead in Open mode or edit the filename in Save mode.

Constructed with “accessible roots” — the workspace-bound paths the caller’s sandbox already allows. FilePicker::can_navigate_to gates every path mutation against them so the user can’t .. out of the sandbox boundary.
