/**
 * Anti-pattern validator (#1888).
 *
 * Runs the graph's `anti-patterns.json` selectors over Eddie markup and
 * reports each hit with the reason and the fix the owning component's
 * `@antipattern` tag authored. Structural rules like "a hero never sits in a
 * layout container" and "every grid child is a grid item" used to live only
 * in realtime-ui's prompt and CLAUDE.md's Common Mistakes; this is the
 * mechanism that makes them refusable.
 *
 * Scope mirrors `SlotContractValidator`: `.html` files whole, and the Lit
 * `html\`…\`` template regions of `.ts` / `.tsx` files. `.njk` / `.vue` reach
 * it as `.html` virtual documents from `eddie_validate_file`.
