Description

This PR adds a new article to the flutter-concepts documentation explaining the core three-tree architecture of Flutter (Widget, Element, and RenderObject trees).

The article is written in a relaxed, beginner-friendly tone to help users understand why Flutter uses this architecture instead of a DOM-like structure to maintain high-performance 60/120fps rendering.

Highlights:

  • Added architecture-trees.mdx under src/content/docs/flutter-concepts/.
  • Included a Mermaid diagram to visually map out the relationships between the three trees (explicitly styled for visibility in both light and dark modes).
  • Broke down the distinct responsibilities of Widgets (Blueprints), Elements (State Managers), and RenderObjects (Workhorses).
  • Added a dedicated section demystifying BuildContext by tying it directly to the Element tree, providing a practical connection to the code developers write every day.
  • Placed correctly in the Astro sidebar (order 5).

Getting closer but this still has some aspects of a medium article in it 😉
