/* cpsboost.com — design system
   "Power Surge": a genuine retro-arcade palette (dark, magenta-tinted
   background — never neutral gray — with ONE dominant saturated accent, one
   secondary, and a third reserved strictly for rare celebratory moments, per
   how real arcade marquee art and CRT-era UIs actually use color). System
   font stack (zero external font requests) — the arcade feel comes from
   glow, chunky notched panels, scanlines, and motion, not from a webfont. */
