fonts-registry.yaml

# fonts-registry.yaml — Register custom fonts for PDF and EPUB output
#
# Place your .otf font files in this fonts/ directory alongside this file,
# then add entries below. Keystone will pick them up automatically — the
# font becomes available as a fontfamily value in pandoc.yaml and as a
# family value in .font divs/spans.
#
# Required fields:
#   main.file   — Filename of the regular-weight .otf file
#   css         — Font-family stack for EPUB/HTML. The first quoted value
#                 becomes the @font-face family name; the rest are fallbacks.
#                 Uses CSS font-family syntax:
#                 https://developer.mozilla.org/en-US/docs/Web/CSS/font-family
#
# Optional fields:
#   main.bold        — Bold variant filename
#   main.italic      — Italic variant filename
#   main.bold_italic — Bold-italic variant filename
#   main.path        — Absolute path to font files (default: /keystone/fonts/)
#   command          — LaTeX command name (auto-generated if omitted)
#   sans             — Registry key of a sans-serif companion from the same
#                      type family. When used as the document font, Keystone
#                      also sets the sans-serif font to this companion.
#
# Example — serif with all variants + sans companion:
#   my-serif:
#     main:
#       file: MySerif-Regular.otf
#       bold: MySerif-Bold.otf
#       italic: MySerif-Italic.otf
#       bold_italic: MySerif-BoldItalic.otf
#     css: '"My Serif", "Georgia", serif'
#     sans: my-sans
#
#   my-sans:
#     main:
#       file: MySans-Regular.otf
#     css: '"My Sans", "Helvetica Neue", sans-serif'
#
# Example — minimal single-weight font:
#   my-display:
#     main:
#       file: MyDisplay-Regular.otf
#     css: '"My Display", "Georgia", serif'
