3. High-Level Hierarchy & Key Control Anchors

Whole-Window DWM Backdrop (backgroundTranslucentEffect: acrylic):
- Bridges the gap between modern XAML chrome and classic Win32 file views. Applying acrylic makes the entire window canvas translucent.
WinUI 3 Tab Control (FileExplorerExtensions.FileExplorerTabControl):
- Houses the open folder tabs. Individual tabs (TabViewItem) feature visual states (Normal, PointerOver, Selected, Pressed) that can be styled into floating glass pills.
Address Bar & Search Box:
- Grid#FileExplorerAddressBarGrid and AutoSuggestBox#FileExplorerSearchBox can be styled with frosted fills, subtle rim borders, and rounded corners (set CornerRadius).
Command Bar Toolbar (CommandBar#FileExplorerCommandBar):
- Modern replacement for the classic ribbon containing Cut, Copy, Paste, Share, and Delete actions.
