/*
 * ═══════════════════════════════════════════════════════════════
 * PALETTE JUSTIFICATION
 * ═══════════════════════════════════════════════════════════════
 * This palette draws from the visual language of boutique design
 * agencies and premium professional services. The deep navy (#0c1222)
 * conveys authority and depth without the harshness of pure black.
 * The warm gold accent (#d4a74a) adds a single point of warmth and
 * sophistication — evoking craftsmanship and precision. The neutral
 * grays (slate scale) provide a clean, readable body while maintaining
 * visual calm. This combination says: serious, skilled, trustworthy.
 *
 * TYPOGRAPHY
 * DM Serif Display — distinctive, editorial serif for headings that
 *   conveys refinement without being stuffy.
 * Inter — highly legible, modern sans-serif for body text.
 * Noto Sans Arabic — clean, well-hinted Arabic typeface that pairs
 *   harmoniously with the Latin fonts above.
 * ═══════════════════════════════════════════════════════════════
