 * Dialy – Diabetes-Begleiter (dark by default, optional light mode; offline-first).
 *
 * Secrets are NEVER hard-coded here. Public, client-safe values
 * (Supabase project URL + anon key) come from environment variables
 * and are exposed via `extra`. A missing value simply disables sync /
 * auth and the app keeps running fully offline.
 *
 * IMPORTANT: only the Supabase *anon* key belongs in the client.
 * Never put a service-role key or DB credentials here.
