/* =====================================================================
   cyber.css - cyber-glitch accents for the portal's arcade moments.
   Every selector is gated behind body[data-cyber], which Portal.boot
   sets from DATA.flags.cyber (js/data.js). Flip that flag to false and
   this whole file is inert. The pastel base of the portal is untouched;
   only the high-energy surfaces (game boot screen, pop reveal, the
   scoreboard window) pick up the glitch language. The 3-2-1-GO digits
   inside the minigame iframes are styled in their own files, gated by
   the shared.cyberFx tuning knob.
