// forms-sync.jsx
// Fire-and-forget Google Forms POST so completion + packet records pool
// across student devices (in addition to the local localStorage cache).
// All fetches use { mode: 'no-cors' } — Google Forms doesn't return CORS
// headers, so the response is opaque. Records still land in the form's
// response Sheet either way.
