# Node.js + fonts: whiteboard frame mode's render-service/ (own README
# there) runs as a second process in this same container rather than a
# separate compose service -- it's a lightweight, stateless, localhost-
# only sidecar with nothing worth independently scaling or restarting.
# NodeSource's setup script is used instead of Debian bookworm's own
# apt Node package, which is both older than jsdom's minimum (20.19+)
# and inconsistently available. fonts-dejavu-core gives the sidecar's
# SVG rasterizer something to render whiteboard text with.
