Solutions

1. Wait for the UI to fully draw before pressing pane-switch keys.
2. Avoid resizing the terminal to degenerate sizes while the TUI is open.
3. Update to the latest dive; pane initialization ordering has been hardened across releases.
4. If it persists, capture the wrapped gocui error and file an upstream issue with terminal info.

When it happens

Trigger: Pressing the next-pane keybinding before the initial layout has registered all three views, or after a layout change dropped a view; can also fire if view names get out of sync with what gocui has created.

Common situations: Rapid keypresses during application startup; extreme terminal resizes tearing down views; custom builds where a view was renamed but the pane-cycle code was not updated.
