/* --- SELF-HOSTED FONTS -----------------------------------------
   Bundled locally (frontend/fonts/) instead of calling Google Fonts
   on every page load. Exo 2 is a variable font -- Google serves one
   file per subset covering the whole weight axis, so a single
   @font-face with a weight range covers every weight this app uses.
   IosevkaTerm ships as static per-weight files, so each weight this
   app actually uses (400/600/700) gets its own @font-face pinned to
   that exact weight. Latin + Latin Extended subsets only (no
   cyrillic/greek/vietnamese -- this app's text is English/ASCII). */
