• 💰 Wallet system — deposit funds, pay for plans (hourly/monthly/yearly)
• 📊 Live logs & deployment history with rollback
• 🔒 Environment variables managed as Kubernetes Secrets
• ⚙️ Resource controls — CPU, memory, replica count

Security

• JWT access + refresh tokens with configurable expiry
• Bcrypt password hashing (12 rounds)
• Helmet HTTP security headers
• RBAC role-based route guards (@Roles(UserRole.ADMIN))
• Namespace isolation — each user deploys to their own K8s namespace
• Secrets — env vars stored as K8s Secrets, never in plain manifests
• Input validation — class-validator on all DTOs
