+**Why show/host/time-temp are plain Text, not Marquee:** pixlet's Marquee
+runs its own internal scroll-cycle animation regardless of whether the text
+actually needs to scroll, and combining multiple Marquees with very
+different cycle lengths in one Root desyncs them — confirmed via an
+isolated repro where a short Marquee'd line intermittently collapsed to a
+single character on frames where the long title/artist marquees were
+mid-cycle. Only title/artist (which actually benefit from scrolling for
+long names) use Marquee; the shorter supplementary fields use plain
+Text/Row and just clip if too wide, which is an acceptable tradeoff.
 
 **Progress bar caveat:** the now-playing API reports track `duration` but
 not elapsed/remaining time, so the app tracks playback position itself —
