/* ============================================================
   God's Church — Main Stylesheet (v6 / Crusader)
   ============================================================
   The foundational design system. Tokens, base, components,
   animations. Premium-game-meets-cathedral aesthetic.

   Loaded by every page. Each subsequent stylesheet
   (landing.css, leaderboard.css, app.css) extends this.

   Touch targets: 44px minimum everywhere.
   Motion: punctuated, not constant. Respects prefers-reduced-motion.

   v6 CHANGES:
   - Cross icon rebuilt as a proper SVG element with a gold
     gradient fill. The previous build relied on the Unicode glyph
     ✟ which Android/iOS render at very different weights — that's
     why the cross looked "small and weird" on phones. Now it's a
     pixel-perfect SVG that scales cleanly at any size.
   - Cross size bumped on mobile (was 1.25em, now 1.5em) so it
     reads as a proper logo mark rather than a tiny ornament.
   - "Sign up" button on mobile uses tighter padding (var(--s-2)
     var(--s-3)) so it doesn't dominate the nav. Content links get
     their breathing room back on tablets too.
   - Restored Leaderboard / About links on tablets (480–640px);
     they only hide on true phones now (≤480px).

   v5 CHANGES (preserved):
   - Mobile nav simplified at narrow widths

/* ============================================================
   10. NAVIGATION
   ============================================================
   v6 strategy:

   The cross icon now ships an inline SVG (background-image data URI)
   that renders identically on every browser and OS. No more reliance
   on the Unicode ✟ glyph that Android renders as a tiny block, iOS
   renders as a serif glyph, and Windows renders as something else
   entirely.

   The icon is sized via `width/height` directly so it's predictable
   across breakpoints. The gold gradient and glow come from CSS, not
   the icon — easier to maintain.

   Mobile nav breakpoints:
     - >640px: all nav items show (brand + links + auth)
     - 481–640px: tablet width, secondary links may compress, Sign up
                  button uses tighter padding
     - ≤480px: phone width, Leaderboard / About hide entirely (still
                  reachable via the footer on every page), nav reduces
                  to [brand] [Sign in] [Sign up]
