+# This workflow performs basic checks:
+#
+#   1. run a preparation step to install and cache node modules
+#   2. once prep succeeds, lint and test run in parallel
+#
+# The checks only run on non-draft Pull Requests. They don't run on the main
+# branch prior to deploy. It's recommended to use branch protection to avoid
+# pushes straight to 'main'.
