// also works when previewed locally, hosted on GitHub Pages under a subpath,
// or dropped behind any other static host without rewriting paths.
//
// The docs corpus and screenshots now live inside this project (under
// `./docs/` and `./public/screenshots/` respectively), so there is no longer
// any cross-workspace alias — `exocore-docs/` builds standalone.
