/* ===== TYPEFACE =====
   Heebo, self-hosted from /fonts rather than pulled from Google Fonts.
   Two reasons: no third-party request means no visitor IP leaves the site
   (privacy.html names FormSubmit as the only processor), and it saves a DNS
   + TLS round trip before first paint. One variable file per subset covers
   weights 400-900, which is the full range the site uses.
   Arrows (U+2190/2192) and ✕ fall through to the system stack by design -
   they sit in Google's "symbols" subset, not worth 30KB for four glyphs. */
