/* Korbel.ai — Fonts
   One family alias: 'Korbel Sans'.
   - Apple platforms resolve local Helvetica Neue faces (no download).
   - Everywhere else, TeX Gyre Heros (GUST licence, ./GUST-FONT-LICENSE.txt) is
     served — a URW Nimbus Sans / Helvetica-metric clone, so layout is identical.
   - Heros ships 400/700 only: weight 500 renders as regular and 600 as bold on
     non-Apple platforms — the same collapse Arial had, but with brand-correct
     letterforms. Apple users keep true Medium at 500.
   Consumers should use var(--font-sans) (typography.css), which now leads with
   'Korbel Sans'. */
