/**
 * STRUCTURED TEXT TYPE SYSTEM FOR DATOCMS
 *
 * This module defines a comprehensive type system for handling DatoCMS structured text fields,
 * which are rich text documents that can contain embedded blocks and inline elements.
 *
 * The challenge we're solving:
 * - DatoCMS structured text can contain "blocks" (embedded content items) in bloth 'block'
 *   and 'inlineBlock' nodes
 * - By default, CMA responses contain blocks as string IDs (lightweight references)
 * - With ?nested=true parameter though, API responses contain blocks as full item objects
 *   (which in turn can contain other blocks)
 * - For CMA requests, blocks can be represented as:
 *   1. String IDs (referencing existing items)
 *   2. Full item objects with IDs (for updates)
 *   3. Item objects without IDs (for creation)
 *
 * This creates a need for different type variants for the same conceptual data structure.

 * - Include full block objects for updates
 * - Omit IDs for new blocks being created
