   Subset from the OFL-licensed variable fonts published at
   github.com/google/fonts (see OFL-*.txt in this directory).

   Subsets carry latin + typographic punctuation and preserve the real
   OpenType features styles.css relies on:
     · Source Serif 4  — smcp, c2sc, onum, lnum, tnum, zero (true small
       caps + oldstyle figures; no more browser-synthesized small caps)
     · JetBrains Mono  — zero (slashed zero), lining/tabular by default
     · Fraunces        — variable opsz / SOFT / WONK axes kept live
   Family names match styles.css exactly; it needs no changes.
