-# Full workspace install (clone + Docker image + rosdep + colcon + yarn) plus a
-# non-interactive launch smoke test, on both x86_64 and ARM64 GitHub-hosted runners.
+# Pixi + RoboStack workspace install (clone + colcon + yarn) and a headless launch
+# smoke test on Linux, macOS, and Windows GitHub-hosted runners.
 #
-# - DEV=false  -> install.sh uses `url_https` from config/repos.json (sub-repos are public).
-# - CI=true    -> install.sh skips the host `xhost` check (no GUI on runners).
-# - variant=arm runs on `ubuntu-24.04-arm` with `./install.sh --arm`; the built image
-#   is then verified to be linux/arm64 (linux/amd64 for the default variant).
-# - Runner OS (22.04 or 24.04) is only the CI host. ROS 2 Jazzy always runs inside
-#   Noble-based images (`ubuntu:24.04` + `ros-jazzy-*` packages; tagged `lucy_ros2:jazzy`).
-# - `ubuntu-24.04-arm` is GitHub's hosted ARM64 runner label; there is no 22.04-arm
-#   standard runner. The container OS stays Noble (24.04) regardless.
-# - The launch smoke test uses `./launch_lucy.sh --headless <command>`, which runs a
-#   single command inside the container (no control panel, no auto Gazebo/RViz).
+# - DEV=false  -> install.sh uses url_https from config/repos.json.
+# - ./install.sh --skip-build clones sub-repos; colcon build runs via pixi run build.
