			// internal/frontend/desktop/linux/window.c:571) calls gtk_drag_dest_unset(webview)
			// when this is set, so the widget stops being a GTK drop destination — and then

			// fire on a widget that IS a drop destination, and Wails never calls
			// gtk_drag_dest_set() to restore it.
			//
			// ⚠️ IT MUST STAY FALSE, and it is HALF of a pair. The other half is the file-drop
			// guard in the XSWD bridge (server_manager.go), which cancels dragover inside the
			// TELA frame. Measured 2026-08-09, both halves are load-bearing:
			//
			//   true            → no drag events reach any document; a dropped file is ignored,
			//                     and OnFileDrop never fires, so nothing can deliver it.
			//   false, no guard → an uncancelled dragover means WebKit never dispatches drop at
			//                     all; it performs its default instead and NAVIGATES the whole
			//                     webview to the file, with no way back.
			//   false + guard   → drop is dispatched in the frame and cancelled, and OnFileDrop
			//                     delivers the real path to Browser.svelte.
			//
			// The DOM alone is not enough on Linux and cannot become enough: the drop event
			// fires but arrives EMPTY (types=text/uri-list,text/html, files.length 0, empty
			// text/uri-list). The native channel is the only source of the bytes.
