+# IPCR Forge: builds the forge service's image (forge/Dockerfile) for every v* tag pushed to this repository's Gitea copy, and pushes it
+# to the forge's staging registry; IPCR imports it from there within a minute and publishes it on
+# IPFS under the forge's name (<forge>/ipcr/ipcr-forge, and ipcr-forge at the root).
+#
+# GitHub ignores .gitea/ (it runs .github/workflows/image.yml → ghcr.io), and Gitea ignores
+# .github/ as soon as this folder exists: one repository, one workflow on each side.
+#
+#   runs-on: ipcr              the forge's own runner, the only one that reaches the staging registry
+#   localhost:5000             that registry, logged in to as this repository (IPCR_PUSH_TOKEN, a
+#                              secret the forge sets on every repository allowed to publish)
+#   network=host               so buildx's builder can reach it too
