"""Fullscreen in-app image view (Features/Major: "Different display in
middle" — fullscreen image, no stretch). Fills Browser's file-area Container
in place of the entry list, same mechanism as Editor.py's EditorView. Just
fit-to-window display — no zoom/pan, matching what was actually asked for."""
