# syntax=docker/dockerfile:1
# nir-rs — published image for GHCR + Docker Hub.
#
# Builder: cargo test --all-features + release example with system libhdf5.
# Runtime: Rust pin + libhdf5 + source (no target/) + example binary.
# WORKDIR stays /src so env!(CARGO_MANIFEST_DIR) from the builder still finds
# tests/fixtures. Non-root user owns /src so cargo can recreate target/.
# No Python (AGENTS.md).
