# Single Responsibility

Each function should do exactly one thing and do it well. Classes should have a single, focused purpose. If a function name requires "and" or "or" to describe what it does, split it. When a class handles multiple concerns (e.g., data access AND business logic AND formatting), separate these into distinct classes.
