   Now-playing island
   Persistent, top-anchored playback control for sent audio/ytdlp/YouTube
   bubbles. Lives outside #messages entirely (position:fixed against the
   viewport, not the scroll container) — the whole point is staying
   reachable regardless of scroll position. Driven exclusively through
   NowPlaying/Island in index.js; nothing else should toggle these classes
   directly. "Live" (--success green, same convention as .is-playing on
   music-panel rows and the online status dot) means audibly playing right
   now; the pill itself persists whether playing or paused, so pausing and
   scrolling away doesn't lose the session.

   Two states, one element. Collapsed is the original compact pill —
   thumbnail, title, playpause, close. Clicking the pill (or tapping, on
   touch) morphs it into a full playback surface: the same header on top,
   a big playpause, a real seekbar, and a "Go to message" button revealed
   underneath. The morph is a single .np-expanded class toggle; every
   dimension that changes (height/width/border-radius/padding/the art's
   own size+shape) is an explicit, fixed target on both ends so the
   transition is a plain, reliable CSS animation rather than anything
   measured/animated to "auto" at runtime.
