The satisfies operator validates that an expression matches a type without changing the inferred type. This is different from type annotations (:) which widen the type.

| Annotation Style | Type vs Value | Use Case |

| : Type (colon) | Type wins | Need wider type for reassignment | | satisfies Type | Value wins | Need validation + narrow inference | | as Type | Lies to TS | Escape hatch (use sparingly!) | | No annotation | Inference | Most common - let TS infer |
