## Overview

Care Unlimited is a content-driven static website: an editor changes Markdown pages, shared settings, images, and videos; the build assembles those into pages and a shared site shell. The graph follows the documented page/block model and sampled build, rendering, media, and shell code. Some capabilities—such as individual block renderers—are represented by their source directory because their implementation was not excerpted.

Main entry points: [`build.mjs`](https://github.com/samdeupta/careunlimited/blob/main/build.mjs) (Build entry), [`src/content.mjs`](https://github.com/samdeupta/careunlimited/blob/main/src/content.mjs) (Content loader), [`src/page.mjs`](https://github.com/samdeupta/careunlimited/blob/main/src/page.mjs) (Page assembler), [`src/shell.mjs`](https://github.com/samdeupta/careunlimited/blob/main/src/shell.mjs) (Shared site shell)
