/**
 * ============================================================================
 * Q-INFINITY DESIGN THEME v3.0.0
 * ============================================================================
 *
 * Futuristic Corporate Minimalist — the enterprise-facing QENEX identity.
 * Replaces sovereign-v31.css as the active production theme.
 *
 * Design principles:
 *   1. Clean elevation, no neon glow
 *   2. Hairline borders (rgba white-alpha)
 *   3. Frosted glass (blur 8px, not 20px)
 *   4. Subtle gradient shifts, not radial nebulas
 *   5. Typography with 0.01em letter-spacing crispness
 *   6. translateY(-2px) hover lift, no glow pulse
 *
 * Load AFTER tokens.css and any site-specific CSS.
