+# Cloudflare's Git-integrated Workers Builds never produced a green deploy
+# (every run since 2026-07 failed, including the wrangler-config fix in
+# PR #68; build logs are only visible in the CF dashboard). This workflow
+# owns the deploy instead, so a broken build/deploy is a visible red check
+# here. Requires repo secret CLOUDFLARE_API_TOKEN ("Edit Cloudflare
+# Workers" token template). The dashboard Git integration should be
+# disconnected once this is green, so the two paths don't race.
