# Gitea Actions runner image for trx-rs CI (host-executor / "Pattern B").
#
# All build dependencies, the Rust toolchain, Node.js (for JS actions such as
# actions/checkout and actions/cache) and the `reuse` tool are baked in, so CI
# runs skip the per-run apt/rustup install cost. `sudo` is present so the
# existing workflow's `sudo apt-get ...` / rustup steps remain valid — they
# just become fast no-ops because everything is already installed.
