Static-print substitute for the interactive tabbed-tutorial control ("Node.js / Python / Ruby" tabs, "Linux / macOS / Windows" tabs). Picks one canonical branch, lays it out in full, and demotes the alternates to a compact appendix block. Two variants: `tabs-static` shows tab chrome at the top with the selected tab highlighted (so the reader can see all options exist); `branched-list` skips the chrome and presents the choice as inline branched prose.
