   beat-the-quant.css — the 1v1 duel "Beat the Quant".
   Ported from the prototype's inline <style>, scoped under #btq-root (native
   CSS nesting) so the duel's generic class names (.arena/.move/.field/.btn…)
   never collide with the app. #btq-root is a full-screen fixed overlay above
   everything (Kurus 199, modals 300, toasts 400).
