Quick Start

You can run this app locally easily.

Option 1: Python Simple Server

If you have Python installed:

cd web
python3 -m http.server 3000
# Open http://localhost:3000

Option 2: Drag & Drop

Since it's a static site, you can technically just drag web/index.html into your browser, though some features might require a local server depending on browser security policies.
