iOS 27 introduces the `accessibilityLinkedGroup` SwiftUI modifier, which lets developers connect multiple separate text views so VoiceOver and Speak Screen navigate across them seamlessly as a single continuous reading experience.
ā¢ Eliminates the dead-end VoiceOver gap between separate text views (paragraphs, pages) when using line/word/character rotor navigation
ā¢ Enables Speak Screen and VoiceOver Read All to flow continuously through paginated or split-paragraph content without stopping
ā¢ Pairs with the existing `causesPageTurn` trait and `accessibilityScroll` to build a full audiobook-quality accessible reading experience
