/* ----- Google Fonts substitute for AvantGardeCTT -----
   AvantGardeCTT is a Cyrillic-extended clone of ITC Avant Garde Gothic
   — a geometric sans built on perfect circles and straight strokes.
   Jost is the closest free, multi-weight match on Google Fonts
   (geometric sans, similar x-height, very close letterforms).
   FLAG: swap in the real AvantGardeCTT .otf/.ttf files when available.
