/* ============================================================
   KODA KARAOKE LIVE — shared visual system
   Wears "La Sala", the language of the private-rooms app, so the
   two karaoke products read as one family: near-black ground,
   depth carried by surface value instead of borders, one green
   for the primary action and for what is live, and nothing square.
   Structure, copy and behaviour are unchanged — only the skin.
