A whole strength-training app in one HTML file — no build, no login, no server. Identified & scoped — packaging next.

24 interactive classes on shipping real tools with Claude Code and a terminal — the same process that built this shelf, not a drag-and-drop toy track.
Every class ends with a working artifact you keep. The proof it works? You're looking at it — this whole shelf was built that way.
