   GUESSING GAME — Design: "Arcade Ticket" (aligned to the reference site)
   Palette:  --primary (petrol/teal) / --secondary (blue) / --accent (gold)
             --card-bg (ticket/card surfaces) / --panel-dark (dark menu bars)
   Look:     neo-brutalist cards — thick dark border + hard offset shadow,
             pill buttons that "lift" on hover, gradient teal→blue headers.
   Display:  "Bungee" / "Fredoka" — big headlines only
   Body:     "Poppins"
   Numbers:  "IBM Plex Mono" — room code, points, inputs (counter look)
