This document discusses a case study of implementing a single content type called "Any Page" using Drupal. It describes how a single content type can simplify content creation and management by allowing pages to evolve more flexibly compared to having separate content types. The implementation uses Entity Construction Kit to create custom entity types for "Any Block" reusable content blocks and "Option Types" for categorizing blocks and pages. Fields on the "Any Page" content type allow assembling pages by referencing these custom block entities in regions like main content, sidebar, etc. This provides a more flexible and future-proof way to model content versus traditional separate content types for each page variation.
