+import SwiftUI
+
+/// A reusable component for triggering infinite scroll loading.
+///
+/// Place this at the end of a list to automatically trigger loading more content
+/// when scrolled into view. Shows a loading indicator while content is being fetched.
+///
+/// Usage:
+/// ```swift
+/// LazyVStack {
+///     ForEach(videos) { video in
+///         VideoRowView(video: video)
+///     }
+///     
+///     LoadMoreTrigger(
+///         isLoading: isLoadingMore,
+///         hasMore: continuation != nil
+///     ) {
+///         Task { await loadMore() }
+///     }
+/// }
+/// ```
+struct LoadMoreTrigger: View {
+    /// Whether content is currently being loaded.
+    let isLoading: Bool
+
+    /// Whether there is more content available to load.
+    let hasMore: Bool
+
+    /// Action to perform when more content should be loaded.
