+// Link checker driven through linkinator's programmatic API.
+//
+// We do NOT shell out to `npx linkinator`: linkinator@6's CLI runs `await main()`
+// at the top level, and on Node 22 the event loop can empty while that await is
+// still pending, aborting with exit 13 ("unsettled top-level await") after
+// fetching only `/`. That is a deterministic crash of the CLI, not a broken
+// link, and it cannot be retried away (see #58). The LinkChecker class below is
+// unaffected, and we drive it with `.then()`/`process.exit` rather than a
+// top-level await so our own process can never hit the same foot-gun.
+//
+// Usage:
+//   node scripts/check-links.mjs <url> --internal          # skip every off-host link
+//   node scripts/check-links.mjs <url> --config <file.json> # use a linkinator config
