Dynamic CMS section system

Homepages built on a CMS typically require per-content-type layout logic — a new section means new code. This project replaces that with a reusable section renderer that maps any content type to a homepage layout through a shared interface.

The system is tagged stable — meaning it has been used across content types without requiring structural changes. That stability is the signal that the mapping contract is well-defined, not just that the code runs.

Status: stable. The renderer handles any content type the CMS produces without per-type layout intervention. New content types slot in through the existing mapping layer rather than requiring new layout code.
