/* === ZaDeteto 2.0 — Self-hosted fonts ===
 *
 * Replaces Google Fonts CDN with locally-hosted woff2 files.
 * Why self-host:
 *   1. GDPR — Google Fonts CDN sends visitor IPs to Google. A 2022 German
 *      court ruling found this violates GDPR for sites without explicit
 *      consent. Self-hosting eliminates the risk for our EU audience.
 *   2. Performance — one fewer DNS lookup + cross-origin handshake per
 *      page load. Lower TTFB and faster first-paint on slow networks.
 *   3. Reliability — site renders correctly even if Google Fonts is down.
 *   4. Privacy — no third-party tracking of which fonts our visitors load.
 *
 * Body font: Inter (replaces DM Sans) — full Cyrillic + Latin coverage.
 *   DM Sans has NO Cyrillic glyphs, so the previous setup silently fell
 *   back to system fonts (Segoe UI / San Francisco / Roboto) for ~95% of
 *   our content. Inter has the same modern geometric-sans aesthetic AND
 *   ships Cyrillic glyphs, so Bulgarian text now actually renders in our
 *   chosen typeface.
 *
 * Display font: PT Serif (replaces DM Serif Display) — full Latin + Cyrillic.
 *   DM Serif Display had no Cyrillic, so Bulgarian headings were rendering
 *   in the system serif fallback. PT Serif is a more readable, editorial-style
 *   serif (less dramatic than DM Serif Display, but consistent across both
 *   scripts). Registered under both 'PT Serif' AND 'DM Serif Display' as an
 *   alias so existing CSS like `font-family: 'DM Serif Display', serif`
 *   transparently picks up PT Serif without rewriting.
 *
 * font-display: swap — show fallback text immediately while font loads,
 * then swap once ready. Eliminates FOIT (flash of invisible text).
 *
 * unicode-range — browser only downloads the subset that contains the
 * characters used on the current page. Cyrillic users skip Latin-Ext,
 * Latin users skip Cyrillic, etc. Subset coverage matches Google Fonts'
 * v20 encoding.
