Dismissing any SwiftUI sheet while a .navigationTransition(.zoom) is
registered traps inside UIKit's _UIZoomTransitionController on the Mac
presentation path (macOS 26.4.1, builds 259/261 crash reports). The
same code path is stable on iOS and iPadOS, so this is an Apple
framework bug on Mac that can only be avoided.
Gate both zoom-transition modifiers on a cached runtime check for
isMacCatalystApp / isiOSAppOnMac so the Mac build falls into the
existing no-op branch while iOS and iPadOS keep the zoom animation.
iOS 27 changes the default scroll edge effect style to hard, which
draws a sharp cutoff line over the channel banner and video info
gradient extending under the toolbar.
Colorful shortcut cards now color by grid position instead of shortcut
identity, so colors stay in the same slot when shortcuts are reordered.
Adds a Palette option (Classic default, plus Sunset, Meadow, Berry,
Grape) and a Custom palette with a swatch-list editor (ColorPicker + hex
fields) and a switchable comma-separated text field. Color is resolved
per position and wraps by palette length, wired via a new
homeShortcutColorfulColor environment value and a Color(hex:) extension.
Sheet dismiss buttons rendered as an iOS-style circular glass "X" on
macOS 26, which looks foreign on the desktop. Add a shared
sheetCloseToolbarItem helper that renders a native text "Close" button
on macOS while keeping the compact icon-only xmark on iOS/tvOS, and
replace the ~14 duplicated inline close buttons across sheets with it.
Extract shared TimeInterval.formattedAsTimestamp replacing 8 identical
formatTime/formattedTime implementations across player views. Remove
unused currentTime parameter from GestureSeekPreviewView. Consolidate
duplicated geometry math in MacOSControlBar into seekPreviewPosition().
