/**
 * **Scaffold generators** — produce ready-to-paste artefacts on request:
 * sample column definitions, a matching demo dataset, and the full theme

 * These are deterministic and local. A language model asked to invent a
 * dataset produces plausible-looking but unusable output (duplicate ids,
 * malformed dates, values that contradict their column type); generating here
 * guarantees the result actually loads into the grid, and costs no tokens.
 *
 * Output is Markdown with fenced code blocks, so the chat panel renders it with
 * a copy button.
