Code Walkthrough

Use a verified tour: establish the real code and output first, then guide attention through one immutable Navi tour.

Prepare The Session

Confirm termctrl, Neovim 0.10 or newer, and navi.nvim are available.
Start Neovim in the project root as a visible foreground session:
```
termctrl run walkthrough -- nvim
```
Use Terminal Control from another process to inspect and drive that same session. Prefer interact through the Terminal Control MCP when available; otherwise use termctrl show, termctrl send, and termctrl wait.
Resize before composing the tour if the visible terminal is too narrow. Keep the size stable while presenting or recording.

The session is ready when the human and agent see the same settled Neovim screen and the agent can inspect it through Terminal Control.
