/* ───── Macron fix for Fraunces ─────────────────────────────────────────
   The Fraunces slice Google Fonts serves *with the SOFT axis* has a broken
   macron: in ā ī ū (and the other composites below) the macron is drawn
   about a quarter-em too far right, so it lands on the next letter —
   "Ilāhī" renders as "Ilaħi‾", "Ḥadīth" as "Ḥadiŧh". No font-feature or
   variation setting fixes it; the same Fraunces *without* the SOFT axis
   is correct. So we load that build under a second family name and route
   only the affected code points to it. Everything else (including all
   dot-below letters: Ḥ ṣ ḍ ṭ ẓ) keeps the full SOFT-capable Fraunces.
   SOFT is a subtle terminal-softness axis; losing it on these few letters
   is invisible next to a struck-through neighbour.
