# pandoc for canonical Markdown -> HTML conversion in the worker.
#
# ffmpeg for the five-second ad renderer, which runs in the worker half of this
# same container: it encodes the compositor's PNG frames into the MP4
# renditions and packages them as fMP4 HLS, and ffprobe is what validation
# decodes to count frames. worker/Dockerfile installs these too, but that image
# is only built when the worker runs as its own Railway service — on this
# project the worker is colocated with the app and THIS is the image that ships,
# so leaving it out here means every render job dies at the first spawn.
