# The quality gate (`cargo xtask ci`: fmt, clippy, heif, tests, parity, layers, assets, wasm) on
# every pull request and every push to main, so the full run happens here rather than on the
# machine of everyone with a branch open. Locally, `cargo xtask ci --quick` checks what a branch's
# changes can break in a few minutes; this job is the merge gate.
#
# Linux only: macOS / Windows test jobs are #1148. Standard GitHub-hosted runner (free for public
# repositories), never a larger one.

  # its `cargo xtask ci` — and every push to main is meant to get a full run.
