1// ════════════════════════════════════════════════════════════════
2// SABR.AI · Sync-Client (v123)
3// ────────────────────────────────────────────────────────────────
4// Spricht mit /api/family (Vercel Serverless). Läuft die App über
5// Tunnel/localhost, wird automatisch die Live-Domain angesprochen
6// (CORS ist serverseitig offen). Graceful: jeder Fehler → die App
7// arbeitet lokal weiter wie bisher.
8//
9// Public:
10//   window.SABR_sync.call(payload)   → Promise<json>
11//   window.SABR_sync.deviceId()      → stabile Geräte-ID
12//   window.SABR_sync.online          → letzter Call ok?
13//   window.SABR_sync.persistent      → Server-Storage dauerhaft?
