Patterns and conventions

Caching Philosophy

Following Epic Web principles:

Weigh the cost-benefit of performance optimizations - Caching adds complexity. Only add cache when there's a clear, measurable benefit. Don't cache "just in case" - cache when you have a real performance problem that caching solves.
