- The stage is sized in dvh (80dvh × 1.25 windowed, 100dvh fullscreen); the viewport-units
contract no longer exempts the player.
- A tap that reveals the bands keeps them pointer-events-none for the double-tap window, so the
second tap of a skip at the bottom is not a seek.
- An arrow on the volume slider wakes the bands, and a keyboard focus in a band holds them
(`holdOnFocus`, `:focus-visible` only, so a clicked button does not pin the bar).
- Next stays mounted (disabled) while the next episode's detail loads, keeping the focus.
