Adapts NASA's "Power of 10" safety rules for high-reliability TypeScript code.

NASA TypeScript Safety Protocol
1. Simple Control Flow
Rule: Avoid complex recursion. Use simple iteration.
Limit: functions should be perceivable on a single screen (approx 50-60 lines). If longer, Refactor.
2. Strict Scope & Initialization
Rule: Variables must be declared in the smallest possible scope (const > let > var).
Initialization: Objects should be fully initialized. Avoid "build-up" patterns where properties are added later (forces consistent Shapes/Hidden Classes).
3. The "No Magic" Rule (Type Safety)
Strict Ban: as unknown as Type. If you need this, your types are wrong.
Strict Ban: any. Use unknown with Type Guards if data is truly dynamic.
Validation: Input data (from API/User) MUST be validated (Zod) at the boundary. Never trust external input.
4. Robust Error Handling
Rule: Check return values. Promises must be caught.
Crash Proof: Critical flows (Payment, Data Save) must have try/catch and recovery logic, not just "log and crash".
