🎯 Design Principles
1. Security First
Price validation server-side. Passwords with bcrypt. Parameterized SQL. Rate limiting on sensitive endpoints.
2. Progressive Enhancement
MVP first (v4.0), then enhance. Every version adds one concept. Ship early, iterate often.
3. Defense in Depth
TypeScript → API Validation → DB Constraints
If one layer fails, others catch it.
