/* Fonts are vendored so the deck runs with zero network. */
/* MXTW sets everything in ABC Monument Grotesk (Dinamo, commercial, not redistributable). The deck uses
   Instrument Sans (OFL, Google Fonts), the closest open grotesk. Its static 400/500/600 instances stand in for
   the requested weights so headlines land on medium like the template: 400 → regular, 500–600 → medium,
   700 → semibold, 800–900 → medium. Geist only fills in arrows and symbols that Instrument Sans lacks. */
