Frontmatter Core – Typed JSON data layer bridging Astro and CMS

Summary: Frontmatter Core generates a typed JSON content model by scanning Astro, Markdown, and YAML files at build time, enabling real CMS systems to consume frontend content without altering the frontend code.

What it does

It scans Astro, Markdown, and YAML to produce a clean, typed JSON Intermediate Representation that CMS adapters can use, operating entirely at build time without runtime dependencies.

Who it's for

Developers integrating static frontends like Astro with real CMS platforms while maintaining control over content models.

Why it matters

It solves the incompatibility between modern frontend content formats and CMS systems by providing a standardized, lock-in-free data layer.
