/**
 * Self-Hosted Core Fonts
 *
 * These @font-face declarations load core fonts (Inter, Sora, DM Sans, Playfair Display)
 * from local /public/fonts/ directory instead of Google Fonts.
 *
 * Benefits:
 * - Eliminates 3-hop font chain (HTML → Google CSS → woff2)
 * - Reduces mobile LCP from 2.4s to target <2s
 * - Enables preloading of critical hero weights (700, 400)
 * - Latin subset only (30-40% smaller than full fonts)
