Reshape the logic branch from a terminal app into a single
self-contained HTML file a non-developer can drive: a labelled
state panel, free-play buttons, and tabbed guided walkthroughs
(scenarios) with the ordered buttons to press underneath each.
The portable pure-logic module still lifts into the real code;
the HTML shell is the throwaway primary source.
