+// The one piece of gamepad-menu machinery shared by the host launcher (GamepadHomeView) and the
+// library coverflow (LibraryCoverflowView): a horizontal, center-snapping carousel driven entirely
+// by a controller (iOS/iPadOS only).
+//
+// The scrolling is pure native SwiftUI — `.scrollTargetLayout()` + `.scrollTargetBehavior(.viewAligned)`
+// snap exactly one item to center, and symmetric `.safeAreaPadding(.horizontal)` (sized off the live
+// container width, so it's correct in an iPad split view too) lets the first and last item reach the
+// middle. The CALLER owns each card's look, including its own `.scrollTransition` — this component
+// deliberately applies none, so a screen can chain the VisualEffect-only transition modifiers without
+// the generic wrapper here pushing the type-checker onto an overload it can't satisfy.
+//
+// Navigation authority: an internal `cursor` (an index), NOT the scroll-position binding, is the
+// source of truth for where the gamepad is. `.scrollPosition(id:)` is a two-way binding and the
+// scroll view WRITES intermediate ids into it while a programmatic animation is in flight — so
+// reading the "current" item back out of it to compute the next one desyncs badly on a fast held
+// stick (each move reads a lagging value and the cursor stalls before the last item). Instead a move
+// advances `cursor` synchronously and points the scroll view at `items[cursor]`; scroll read-back is
+// only allowed to move the cursor when the gamepad hasn't driven recently (i.e. a touch drag).
+//
+// Feedback is dual-channel by design: `.sensoryFeedback` ticks the DEVICE Taptic engine (for a
+// handheld/touch user) and `MenuHaptics` ticks the CONTROLLER (for a couch user holding the pad).
+// Both fire on a move, on confirm, and — for a non-wrapping list — a duller bump plus a short visual
+// recoil when a move is refused at either end.

+// The gamepad-driven home screen (iOS/iPadOS only): a distinct, "10-foot" console-style host
+// launcher shown INSTEAD of HomeView while GamepadUIEnvironment is active — a separate screen built
+// around a center-snapping carousel of hosts, driven from the couch with a controller. No touch is
+// required (a tap still works as a fallback). Scope: browse saved + discovered hosts, connect, and
+// — when the library flag is on — jump into a saved host's library (Y).
+//
+// All the scrolling/snapping/navigation/haptics live in GamepadCarousel; this file is the launcher's
+// chrome. Layout discipline (so nothing is EVER clipped, portrait or landscape): the gradient is a
+// `.background` modifier — NOT a ZStack sibling — because an `.ignoresSafeArea()` sibling expands the
+// stack to full-screen and hands the GeometryReader the full height, laying content out under the
+// status bar / home indicator. As a background it draws behind without affecting layout, so the
+// GeometryReader is sized to the safe area. The title and the controller-glyph hints are pinned with
+// `.safeAreaInset` (top / bottom-leading) — guaranteed inside the safe area and out of the carousel's
+// vertical budget — and the card is sized off the remaining height. tvOS/macOS never mount this view.

+// The gamepad-driven presentation of the game library (iOS/iPadOS only — see LibraryView's
+// `gamepadUIActive` branch): a classic coverflow instead of the touch grid. All the
+// scrolling/snapping/navigation/haptics live in GamepadCarousel; this file is the coverflow card
+// (poster + the 3D recede treatment via `.scrollTransition`), the "now focused" detail panel, and
+// the controller-glyph hints. A steps through covers, A launches the centered title, B closes, and
+// the shoulders (L1/R1) jump a handful at a time through a long library.
+//
+// Layout discipline (so nothing is EVER clipped, portrait or landscape): the gradient is a
+// `.background` modifier — NOT a ZStack sibling — because an `.ignoresSafeArea()` sibling expands the
+// stack to full-screen and hands the GeometryReader the full height, laying content out under the
+// status bar / home indicator. As a background it draws behind without affecting layout, so the
+// GeometryReader is sized to the safe area, and the controller-glyph hints are pinned inside it with
+// `.safeAreaInset(.bottom, alignment: .leading)`. Cover size is then derived from the height that
+// remains, so a tall 2:3 poster + the detail line always fit.
