/* ============================================================
   Somehow Functional — self-hosted fonts
   Served same-origin from /fonts/. No third-party requests.

   Fontsource builds of the upstream Google Fonts sources, latin
   subset, variable where variable exists. All SIL Open Font
   License 1.1 — texts ship in /fonts/licenses/ as OFL requires.

   Families are declared under their plain names (matching the
   font-family declarations already used across the site and the
   tools) so removing Google Fonts needs no other CSS change.
