/* =========================================================
   Living Just Right with LG — Spin the Wheel (G3)
   Tablet / phone portrait, responsive.
   Theme taken from the LG identity + supplied logos:
     LG Active Red #A50034 (grad #D4004A -> #6E0023)
     deep maroon-black backdrop #170209 / #2B0512
     peach #FBD3A5 — matches the AI Home Hunt logo artwork
     Abans purple #7B2382 — partner accent
   No client game art was supplied for this game, so the wheel,
   buttons, game logo and result ticket are all built in CSS.
