Start with the linked core-concepts/kodadot-stack/ and other/kodadot-upcoming.html preview pages, then review the existing NFT standards section referenced in the issue. Identify every SubQuery mention and the standards content needing expansion, including attribution for reused material. Done means the pages link to SubSquid and relevant standards with accurate, checked links.
