// A content type declared as CODE — typesafe, version-controlled, PR-reviewed.
//
// Each field uses the CMS `Schema` field DSL (distinct from the @voltro/database
// column DSL). `defineContentType` resolves this to a descriptor the editor
// introspects to generate its form, and `contentTypeToEntities` (in
// database/schema.ts) compiles the fields DOWN to real `blogPost_drafts` +
// `blogPost_published` columns.
//
// Imported from the MAIN `@voltro/cms` entry because it runs server-side at
// discovery time (schema.ts imports it). The browser-safe field DSL is the same
// object either way — the editor page never imports this file; it fetches the
// resolved descriptor over rpc (content.types).
