/* ---- Self-hosted fonts ----
   Replaces the brand guide's own Google Fonts @import (fine for a
   brand-guide reference page, not appropriate for a production site —
   avoids a third-party runtime request and the associated render delay).
   Inter is loaded as a single variable-weight file (100–900), which is
   the only way to get the brand guide's specified weight 650 without
   approximating it against a fixed static cut. JetBrains Mono ships
   only 400/500, which is all the brand guide specifies for mono use. */
