+- ✅ Development mode (console log namiesto emailu keď BREVO_API_KEY="brevo_test_key")
+- ✅ Production mode (Brevo API integration s messageId tracking)
+- ✅ Všetky sessions sa vymažú po resete (force re-login)
+
+### Výsledné funkcie:
+- ✅ Odoslanie reset emailu funguje (Brevo API)
+- ✅ Token validácia funguje (expiracia, duplicita, použitie)
+- ✅ Reset hesla funguje s kompatibilným scrypt hashom
+- ✅ Email template je pekný a funkčný s correct frontend URL
+- ✅ Development mode bez Brevo API kľúča (console log)
+- ✅ Production ready s Brevo integration
+- ✅ Všetky sessions sa vymažú po resete (security)
+- ✅ Prihlásenie funguje po resete hesla
+
+**Technické detaily:**
+- Email service: Brevo (@getbrevo/brevo SDK)
+- Password hashing: Node.js crypto scrypt (Better Auth compatible)
+- Token storage: PostgreSQL (PasswordReset table)
+- Email delivery: 300/day limit (Brevo free tier)
