# Prerequisites:
#   - rsvg-convert (brew install librsvg)
#   - python3 with plotly, kaleido, numpy, pyyaml
#   - d2 (optional, only needed to re-render D2 -> SVG)
#
# Usage:
#   ./build.sh          # render PNGs from SVGs + heatmap + sweep chart
#   ./build.sh --d2     # also re-render D2 sources to SVGs first
