# render/math/01-math.sh — mathematical & technical symbols (pdfnative 1.5.0)
#
# Registers the bundled math font alongside Latin so that operators, Greek
# letters, set relations and blackboard-bold code points render as real glyphs
# instead of .notdef tofu. pdfnative auto-routes each code point to the font
# whose cmap covers it, so just registering `--font math` is enough.
#
# Prerequisites:
#   - pdfnative-cli installed globally: npm install -g pdfnative-cli
#
# Usage:
#   bash samples/render/math/01-math.sh
