/* Solaiman Lipi — self-hosted Bengali web font.
 *
 * Font files go in: assets/frontend/fonts/solaiman-lipi/
 *   SolaimanLipi.woff2  (primary — best compression)
 *   SolaimanLipi.ttf    (fallback for older browsers)
 *
 * Download TTF: https://www.omicronlab.com/bangla-fonts.html
 * Convert to WOFF2: https://cloudconvert.com/ttf-to-woff2
 * License: Free for personal and commercial use.
 *
 * Performance notes:
 *  - font-display:swap  → page text stays visible while font loads (no FOIT)
 *  - unicode-range      → font binary is fetched ONLY when Bengali characters
 *                         are actually present on the page; Latin/numeric text
 *                         never triggers a download even if this CSS is loaded
 *  - local()            → zero-cost: if the visitor already has Solaiman Lipi
 *                         installed, the browser uses it without any network request
