Searches all dates from Feb 20 to Dec 31, 2026.

✅ Separate paths per shop — Papagou 56, Papagou 76 and Afxentiou 59 each save to their own Firebase path. One shop can never overwrite another.

✅ Admin costs protected — Admin buy costs save instantly to a separate path. Employee saves can never touch them.

✅ Local device backup — Every save also writes to your browser storage. If Firebase is slow on login, your last saved data is restored automatically.

✅ Data never deleted by the app — The app never calls any delete or overwrite on the root database. Only individual shop paths are written.

✅ D_END = 2099 — Date range extends to year 2099, so old entries never drop off.

💡 If data ever looks missing: Wait 15 seconds for Firebase to sync, or press "Re-sync from Firebase" above. Data is never deleted — it is always in Firebase.
