Paper Dashboard — static frontend

Static React dashboard. Fetches JSON from the Apps Script web app deployed in ../Dashboard/.

Setup

1. Visit https://<user>.github.io/Dashboard/#key=YOUR_DASHBOARD_KEY once.
   • The key is read from the URL hash, persisted to localStorage, and the hash is stripped.
2. After that, plain https://<user>.github.io/Dashboard/ works on this device.

To reset the key: open DevTools → Application → Local Storage → delete DASHBOARD_KEY.

Hosting

Repo Settings → Pages → Source: main branch / /Page folder.

Files

• index.html — entrypoint, registers the service worker, mounts React via Babel-standalone (no build step)
• sw.js — cache-first for static assets / CDN, stale-while-revalidate for the GAS JSON endpoint
• manifest.json — PWA bits (install to homescreen, theme color)

Bump CACHE_VERSION in sw.js whenever static assets change to force clients to refresh.
