 # Lint/test use continue-on-error: true so Magrathea failures don't block.

-# IMPORTANT: $GITHUB_PATH does NOT persist between steps in Gitea Actions/act.
+# CONTAINER IMAGE: The build-android job uses a pre-built Docker image
-# Each step is a separate shell. We export PATH="$PWD/flutter/bin:$PATH" in
+# (kryz-ci:latest) that includes Flutter, JDK 17, and Android SDK baked in —
-# every step that uses flutter/dart commands.
+# eliminating 3-5 GB of downloads per job. Build once on the runner host:
+#   docker build -f .devcontainer/ci.Dockerfile -t kryz-ci:latest .devcontainer
+#
+# Estimated impact: 40min -> 5-10min (with pre-built image)
