+# Build the three simplepool container images and push them to the GitHub
+# Container Registry (ghcr.io) — the same registry coinshift-rs publishes to.
+#
+# This job runs only in the canonical LayerTwo-Labs repo (see the `if:` guard
+# on the job), so images land in the org namespace, tagged automatically:
+#   ghcr.io/layertwo-labs/simplepool            (C stratum proxy)
+#   ghcr.io/layertwo-labs/simplepool-dashboard  (Node read-only web UI)
+#   ghcr.io/layertwo-labs/simplepool-payout     (Node Thunder payout worker)
+#
+# Auth uses the built-in GITHUB_TOKEN — no secrets to configure, because the
+# repo lives in the same org that owns the packages (exactly like coinshift).
+# Pull-request runs build the images (to prove the Dockerfiles still work) but
+# do not push; only pushes to main, tags, and manual runs publish.
