# CI builder for the Rust workspace — Ubuntu 26.04 to match the dev/host boxes
# (FFmpeg 8 / libavcodec 62, PipeWire 1.6). Used by .gitea/workflows/ci.yml as the job
# container; rebuilt+pushed by .gitea/workflows/docker.yml.
#
#   docker build -f ci/rust-ci.Dockerfile -t punktfunk-rust-ci ci
#
# The workspace links real system libs at build time (CLAUDE.md "Pinned crate facts"):
# FFmpeg, PipeWire, Opus, GL/EGL/GBM — and libcuda, which has no real driver here; the
# zerocopy path only needs the symbols at link time, so a driver userspace package plus a
# libcuda.so -> libcuda.so.1 symlink stands in for it (CI never executes the CUDA path).
