   Hockey Fantasy Pool — Design System
   NHL-arena look: deep navy ice, red/blue accents. Day/night themes via
   [data-theme]. No external assets/CDN/fonts — system font stacks only.

   Directives structurantes (implémentées intégralement) :
   - Reset minimal + box-sizing: border-box.
   - :root[data-theme="dark"]  : --bg:#0a0e1a; --surface:#111827; --text:#f1f5f9;
     --muted:#94a3b8; --accent:#e11d2e; --accent2:#1e5aa8; --border:#1f2a3f.
   - :root[data-theme="light"] : --bg:#f4f6fb; --surface:#ffffff; --text:#0f172a;
     --muted:#475569; --accent:#c8102e; --accent2:#1e5aa8; --border:#dbe2ee.
   - transition douce (0.25s) sur background/color au changement de thème.
   - Titres : font-stack condensée system (Arial Narrow, Impact fallback) via
     .display { font-stretch:condensed; text-transform:uppercase; letter-spacing:.02em }.
   - .container { max-width:1100px; margin-inline:auto; padding-inline:1rem }.
   - Header sticky, fond translucide + backdrop-filter blur.
   - Nav mobile : .main-nav cachée ≤640px, panneau plein écran quand .nav-open.
   - .btn / .btn-primary (fond --accent, hover translateY(-1px) + ombre), .btn-ghost.
   - .card { background:var(--surface); border:1px solid var(--border); border-radius:14px }.
   - .hero : dégradé radial marine + lignes de glace (linear-gradient répété subtil),
     grand titre .display, sous-titre --muted, deux CTA.
   - .reveal { opacity:0; transform:translateY(18px) } .reveal.visible { opacity:1;
     transform:none; transition:.6s cubic-bezier(.2,.7,.3,1) }.
   - Grilles responsives : .grid-3 (1 col mobile, 2 tablette, 3 desktop), .grid-2.
   - @media (prefers-reduced-motion: reduce) { * { transition:none!important; animation:none!important } }.

   Breakpoints : ≤640px mobile · 641–1024px tablette · >1024px desktop.
