Demo scripts ============ This folder holds small, dependency-free scripts used by the asset viewer showcase. They are ordinary public files, so each one can be opened as source or downloaded from its raw URL. check-frontmatter.mjs is a runnable Node.js example. Give it a Markdown file and it checks that the YAML frontmatter contains both title and description. It intentionally keeps the parser small so the example is easy to read. The neighboring diagrams/ folder contains a visual map of the same asset-link flow: a document reference, its raw public URL, and the generated viewer page.
