# Debian, not Alpine, gives the best trade-offs:
#
# * Official Firefox binaries are built against libc.
# * Debian has a great selection of fonts. (When converting, fonts are rarely
#   embedded in the HTML. If we have the font on our system, we can embed
#   anyway instead of defaulting to a boring font.)
