/**
 * Xenopz Design System - Typography
 * ===================================
 *
 * Implements the full typography system: heading styles (H1-H3), body text,
 * code blocks, and utility classes. Uses fluid type with clamp() for
 * responsive scaling without breakpoint jumps.
 *
 * Font loading: Google Fonts (Barlow Condensed 800, Inter 400/500/600,
 * JetBrains Mono 400/500) with font-display: swap for performance.
 *
 * Reference: .kiro/specs/xenopz-wordpress-website/design.md
 * Requirements: 3.1, 3.2, 3.3, 3.4, 3.5, 27.3
