Coming soon · console-command-trainer pathway
A trainer for the command line you already have. The product is Terminal Teacher. The pathway is console-command-trainer. Three tracks: Browser Console, PowerShell, and Command Prompt. Open a card, read the explain, run it in a sandbox first, and only unlock live execution if you confirm. Chat can sit beside the lesson if you bring your own key. Coming soon — no download yet.
> Sandbox is the default. Live is a lock you open on purpose.
> Command Prompt is the Windows cmd.exe track, not a toy shell.
> Shell tracks are a read-only simulator. Console live runs need an explicit unlock.
