- Open a hidden diagnostics dialog after tapping the header seven times within fifteen seconds.
- Let the diagnostics dialog toggle the pane color/stripe skin on demand.
- Restore the normal app background and pane colors by default.
- Stop Scaffold from preserving the bottom navigation-bar inset while the keyboard is visible.
- Apply bottom navigation padding only when the IME is not open.
- Give each top-level pane a distinct temporary diagnostic color and stripe pattern.
- Give the root app background a separate purple diagnostic color so empty space outside panes is identifiable.
- Hide the terminal output viewport when there are no output lines on a newly loaded level.
- Reduce the minimum output history height so short output does not create a large empty black panel.
- Use the pane surface color for the app background so normal spacing between cards is not black.
