   Akzidenz-Grotesk BQ — the brand-prescribed type family.
   Files live in assets/fonts/. Weights mapped:
      300 Light · 400 Regular · 500 Medium · 700 Bold · 800 XBold · 900 Super
   Italic variants attached where available.
   The "Extended" cut is exposed as a separate family
   (--font-display-ext) for display-only treatments that need
   the wider letterforms.
