# Option A — google/fonts GitHub release trees (OFL sources; pick a tag/commit)
# Comment-only reference URLs (do not curl until you pin a commit + verify OFL):
#
#   # Fraunces variable / static under apache/ofl:
#   #   https://github.com/google/fonts/tree/main/ofl/fraunces
#   #   raw example (PIN A COMMIT — main moves):
#   #   https://raw.githubusercontent.com/google/fonts/<COMMIT>/ofl/fraunces/Fraunces%5Bopsz%2CSOFT%2CWONK%2Cwght%5D.ttf
#   #
#   # JetBrains Mono:
#   #   https://github.com/google/fonts/tree/main/ofl/jetbrainsmono
#   #   https://raw.githubusercontent.com/google/fonts/<COMMIT>/ofl/jetbrainsmono/JetBrainsMono%5Bwght%5D.ttf
#   #
#   # Upstream project pages (also OFL):
#   #   https://github.com/underscript-type/fraunces
#   #   https://github.com/JetBrains/JetBrainsMono
#
# Example curl skeleton (still commented — replace COMMIT and convert TTF→woff2
# with fonttools/woff2_compress; do not commit unlicensed or renamed dumps):
#
#   # COMMIT=________________________________
#   # curl -fsSL -o /tmp/fraunces.ttf \
#   #   "https://raw.githubusercontent.com/google/fonts/${COMMIT}/ofl/fraunces/Fraunces%5Bopsz%2CSOFT%2CWONK%2Cwght%5D.ttf"
#   # # subset + woff2, then:
#   # # cp fraunces-opsz-wght-700.woff2 "$DIR/"
#   # curl -fsSL -o "$DIR/OFL.txt" \
#   #   "https://raw.githubusercontent.com/google/fonts/${COMMIT}/ofl/fraunces/OFL.txt"
#
# ---------------------------------------------------------------------------
# Option B — fonts.google.com CSS API (CDN helper; not for production self-host
# of binaries in-repo — use only to discover gstatic file URLs you already
# have rights to cache under OFL):
#
#   # curl -fsSL -A "Mozilla/5.0" \
#   #   "https://fonts.googleapis.com/css2?family=Fraunces:opsz,wght@9..144,600;9..144,700&family=JetBrains+Mono:wght@500&display=swap"
#   # # Then curl each https://fonts.gstatic.com/...woff2 URL into this dir
#   # # with the planned filenames above. Still need OFL.txt from Option A.
