Replace the separate top nav bar and TTS player bar with a single compact sticky header that stays visible while scrolling. Navigation (← back, Prev, Next) and the Listen/Pause button are always accessible. Voice, speed and auto-next settings are moved into a ⚙ dropdown that opens from the header, keeping the reading area clean. A thin status strip below the toolbar shows Buffering/Playing/Error states only when active.
