## Overview

MedInfo is a lightweight medical-blog CMS: staff manage categories and publish posts, while readers browse, search, and view posts. The documented browser pages are served as static files, and the API handles category and post operations backed by SQLite. The graph follows the explicit routes in `server.js`; `app.js` contains a second, overlapping API implementation, and the supplied tree does not include the `bin/www` entry referenced by the start script. UI behavior and the documented editor/image features are not verified in sampled page source.

Main entry points: [`public/admin.html`](https://github.com/naf7111/midinfo/blob/master/public/admin.html) (Admin page), [`public/index.html`](https://github.com/naf7111/midinfo/blob/master/public/index.html) (Post listing), [`server.js`](https://github.com/naf7111/midinfo/blob/master/server.js) (Post endpoints), [`public/post.html`](https://github.com/naf7111/midinfo/blob/master/public/post.html) (Post detail)
