Narrative Element Embedding System

Narrative Elements are intended to function as independent narrative atoms that can later become part of larger Fragments or Chapters without losing their standalone existence. Unlike current CPT integrations that rely on patterns or duplicated content, Elements should support direct rendering of their the_content() output inside larger narrative structures. This task explores implementation approaches including shortcode embedding, relationship-driven rendering, or hybrid synchronization systems that allow Elements to remain independently editable while appearing dynamically inside parent content. The goal is to create a modular narrative assembly system where Elements can evolve independently while still participating in higher-order structures.
