/* The read-aloud player (listen.mjs). An app colours it by setting these on .listen:
   --lst-bg      panel fill          --lst-line    panel and chip borders
   --lst-ink     text                --lst-muted   secondary text, unread subtitles
   --lst-accent  play button, active chapter, scrub bar
   --lst-on      ink on the accent   --lst-chip    chip and speed-button fill
   Rules are scoped under .listen, and button rules name the element, so they outrank a
   page framework's button styles (Clay's button:not(.circle):not(.chip) is 0,2,1). */
