/**
 * PSN Souq — Main Stylesheet v2.0
 * PlayStation-inspired dark design system
 * Surface: Explore
 *
 * Principles:
 * - True black canvas (#000000)
 * - PS Blue (#0070d1) — primary CTA, links
 * - Commerce Orange (#d53b00) — buy actions only
 * - Space Grotesk (display, weight 300) + Tajawal (Arabic body)
 * - 6px radius on cards, 999px pill on buttons
 * - Hairline borders, no blur shadows
 * - Interaction-only motion (150ms)
 * - RTL Arabic-first
