//! GTK/relm4 layer: the panel window, toolbar and file tree.
//!
//! Layout of concerns:
//!
//! * [`app`] — the root [`relm4::SimpleComponent`]: owns the layer-shell
//!   window, the toolbar and tree subcomponents, the status bar and session
//!   state persistence.
//! * [`bookmarks`] — the bookmarks strip docked above/below the panes, plus its
//!   editor dialog.
//! * [`toolbar`] — the "open folder" button and the editable path entry.
//! * [`tree`] — the file tree itself: rendering, keyboard navigation, the
//!   context menu, inline rename, clipboard and trash.
//! * [`props`] — the Properties dialog (metadata and a permissions editor).

/// Detaching alone does not stop a clip: the `GtkMediaStream` (a
/// `GtkMediaFile`) can outlive the widget — a row GTK has removed is freed
/// lazily, and the media cache may still hold it — so it keeps its GStreamer
/// pipeline, audio included, running even after the thumbnail is gone. Pausing
/// first actually stops playback; detaching then releases the widget's
/// reference.
