/* ==========================================================================
   Vice Played Wise — Design System v4 "PLAY THE GAME"
   Concept: a glossy, chrome-neon brand system built around the VPW mark —
   pink to orange to gold to cyan to violet, on near-black, with soft neon
   "smoke" glow standing in for texture instead of a filter. Rounded, glossy,
   confident: casino-chip buttons, gradient-stroke line icons, glow-lit cards.
   Original artwork throughout — no Rockstar/Take-Two assets, logos, or trade
   dress are used or referenced visually anywhere in this system.
