+## Patterns vs Conventions
+
+**Pattern** = prescriptive. "When you face X, do Y." Language-scoped. Follow these.
+
+**Convention** = descriptive. "Project Z does it this way." Context-specific. Study for ideas — applying another project's conventions to yours without understanding their constraints causes harm.
