sanity-singletons

Configure singleton documents in a Sanity Studio using the document.singletons registry. Use when a developer wants a fixed-id document (settings, navigation, footer) edited in place, hidden from the default content list, with no "create new" or "duplicate" affordances — or when migrating a userland singleton implementation or a third-party singleton plugin (e.g. sanity-plugin-singleton-management) to the first-class API.
