wtf is anatomy?

The README for this repository describes a generic full-stack starter template called vinext-starter, built on a framework named vinext, with optional support for Cloudflare D1 database and the Drizzle database toolkit. It does not describe the interactive 3D human anatomy explorer mentioned in the repository's short description, so what follows is based only on what the README itself documents. To use the starter, you need Node.js version 22.13.0 or newer. You install dependencies, then run a development server or a production build with a small set of npm commands. The starter is organized with site code kept under an app folder, a configuration file describing optional database and storage bindings, and an initially empty database schema file that can be filled in and migrated using Drizzle as the project grows. A notable part of the README covers authentication for sites hosted on OpenAI's workspace platform. Pages can read a signed-in user's email from a special request header, and in some cases a full name as well. The starter includes ready-made helper functions for checking whether a visitor is signed in with ChatGPT, requiring sign-in for protected pages, and generating sign-in and sign-out links. The README is careful to note that this sign-in method only establishes who the user is, and that separate access control checks are needed to restrict pages to specific workspaces or users. A short list of npm commands is included for local development, building, testing, and generating database migrations, along with links to the vinext and Drizzle documentation for further reading. Because this README does not mention 3D rendering, human anatomy content, or any anatomy-specific features, this explanation is limited to the starter template functionality actually documented here.
