/*
  dgreat.guide v14 — ground-up stylesheet.
  Design: evolved synthwave. The background is a dim backdrop; the CONTENT
  carries the motion (replays, counter cards, tier deltas, XP).
  Identity kept from v13: void purple base, magenta/cyan neon, sharp corners,
  Orbitron for display, Rajdhani for everything readable.
