/* Avrostay marketing site — shared stylesheet for both locales.
 *
 * Extracted from the two prototype <style> blocks (avrostay-bg.html /
 * avrostay-en.html), which were identical apart from incidental 1-2px font-size
 * drift; unified at the BG values. Tokens mirror the handover's brand-tokens.css.
 *
 * FONTS — two deliberate departures from the handover:
 *
 * 1. Self-hosted, not Google-hosted. fonts.gstatic.com transmits every visitor's
 *    IP to Google; the privacy policy's claim that no visitor data leaves this
 *    server has to actually be true. Also removes 2 DNS lookups + 2 TLS
 *    handshakes + a render-blocking cross-origin request from the critical path.
 *
 * 2. Onest replaces Space Grotesk as the display face. Space Grotesk ships NO
 *    Cyrillic (latin, latin-ext and vietnamese only), so every heading on the
 *    Bulgarian page — the default locale and primary market — silently fell back
 *    to a system font in the prototype. Onest is the closest geometric grotesk
 *    with full Cyrillic. Owner-approved deviation.
 *
 * Each face is split latin/cyrillic by unicode-range, so the EN page downloads
 * ~90KB and never fetches the Cyrillic files at all. Onest and IBM Plex Sans are
 * variable (one file spans the weight range); IBM Plex Mono is static, hence one
 * file per weight. Licenses: assets/fonts/OFL-*.txt (both OFL-1.1).
