+# **what?**
+# Nightly releases to GitHub and PyPI. This workflow produces the following outcome:
+# - generate and validate data for night release (commit SHA, version number, release branch);
+# - pass data to release workflow;
+# - night release will be pushed to GitHub as a draft release;
+# - night build will be pushed to test PyPI;
+#
+# **why?**
+# Ensure an automated and tested release process for nightly builds
+#
+# **when?**
+# This workflow runs on schedule or can be run manually on demand.
