# A build context rather than a bind mount, deliberately: a Docker Desktop with
# no shared drives mounts `-v /real/path` as an empty directory, and the
# failure reads as "Cargo.toml is missing" rather than as a mount problem.

# The cache mounts are what make it usable a second time — without them every
# run rebuilds rav1e, ffmpeg-sys and the static libvpl from scratch.
