Agent Skills: explainers

Build an interactive explainer — a standalone web page that teaches one concept by letting the reader play with it. Use when the user says "build an explainer for X", "help me understand Y interactively", or "make a page that demonstrates Z". Ships a minimum HTML scaffold + methodology guide with pointers to reference implementations (dolt-explainer, larry-voice-samples, monitor-explainer, activation-energy-game, religion-evolution-explorer, how-long-since-ai). Prefers GitHub Pages + plain HTML by default; graduates to Vite + TypeScript + React only when interaction genuinely requires it.
