+# A push that breaks a test turns main red and never reaches Pages; the previous

+# manual escape hatch, and the deploy job refuses any ref that is not main.

+# REQUIRES A ONE-TIME SETTING. Settings → Pages → Build and deployment → Source must
+# be "GitHub Actions", not "Deploy from a branch". Until it is, the first run fails —
+# in the build job at configure-pages if Pages was never enabled, or in the deploy
+# job with "Resource not accessible by integration" if Pages still serves a branch.
+# Either way the workflow is correct; the repository setting is what needs to move.
+# The switch cannot be made from here: it needs administration:write, which
+# GITHUB_TOKEN is not. It is reversible — setting Source back to a branch restores
+# the old behaviour and this workflow simply stops being able to deploy.
