Creating reusable container views
summary
Builds a reusable SwiftUI pager called PagerTabStripView using GeometryReader, the new Layout protocol (iOS 16), LazyHStack inside a ScrollView, and an EnvironmentObject-backed data store. Implements tappable “tab” items, a moving indicator, and per-page views that preserve their state when you navigate away. Explains layout math for indicator placement, shows how pages are registered via frames, and proves the library works and composes inside other scrollable containers.
