Frequently asked questions
Does it actually check the file exists?+
Browser tools can't access the local filesystem. Format-check only — verify file existence in your dev environment.
What about query strings?+
Query strings in paths are accepted; they're checked as part of the URL syntax.
Will it work for Astro / Next.js routes?+
Yes. Framework-style paths (`/blog/post-slug`) are accepted as valid relative paths.
