/* Inter Font - Self-hosted
 * Source: Google Fonts (https://fonts.google.com/specimen/Inter)
 * License: SIL Open Font License 1.1
 * 
 * This file contains @font-face declarations for the Inter font family.
 * Weights included: 400 (Regular), 500 (Medium), 600 (Semi-bold), 700 (Bold), 800 (Extra-bold), 900 (Black)
 * 
 * Note: Inter is a variable font, but these files use static instances for broader compatibility.
 * The same woff2 files work for all weights due to Google Fonts' optimization.
 * 
 * font-display: optional - Uses fallback font if web font doesn't load in ~100ms
 * This eliminates "render delay" for LCP optimization (target < 2.5s)
