NEVER Do (Expert Anti-Patterns)

Logic & Architecture

• NEVER hardcode card logic inside UI scripts; strictly encapsulate gameplay effects in Callable objects or Command resources pushed to a LIFO stack.
• NEVER perform board-state calculations (Power/Toughness) in _process(); strictly use Signal-driven triggers or a centralized EffectStack resolver.
• NEVER forget LIFO Stack Resolution; strictly use Array.push_back() and Array.pop_back() to resolve reactions from top-to-bottom.
