# Runtime deps:
#   - cairo provides libcairo so cairosvg can rasterise SVG → PNG.
#   - ttf-liberation gives Liberation Sans Bold at
#     /usr/share/fonts/liberation/LiberationSans-Bold.ttf — exactly where Arch
#     installs it, so dev (shanks) and prod (this container) render with the
#     same font and the posters come out identical.

# All pip deps ship musllinux wheels — no build-deps needed.
