  TODO: Add json+ld data, maybe https://schema.org/APIReference makes sense?
  Docs: https://developers.google.com/search/docs/advanced/structured-data/intro-structured-data
  https://www.npmjs.com/package/schema-dts seems like a great resource for implementing this.
  Even better, there's a React component that integrates with `schema-dts`: https://github.com/google/react-schemaorg
