Couldn't load data.json

This page reads its content from data.json, but the browser blocked the request — usually because the file was opened directly (the address bar starts with file://).

Run a small local server from this folder instead, then reload:

python3 -m http.server 8000
# then open  http://localhost:8000

Once deployed (GitHub Pages, Netlify, Vercel, …) it just works.
