 * The artifact stacks this package understands, and the entry file each one

 *
 * Deliberately data-only and free of runtime imports. The store needs to know
 * which stacks exist and what their entry file is called, but not how to render
 * one — `renderer-registry.ts` binds these stacks to the markdown/HTML
 * renderers, and pulls in prettier, KaTeX and markdownlint to do it. Keeping the
 * table here means reading or listing a bundle never loads a renderer.
