nav▌

Core principle 85% of navigation problems stem from path state management errors, view identity issues, or placement mistakes—not SwiftUI defects.

Introduced in iOS 16 (2022) with NavigationStack and NavigationSplitView, evolved in iOS 18 (2024) with Tab/Sidebar unification, and refined in iOS 26 (2025) with Liquid Glass design.
