+# ============================================================================
+# Install a Gitea Actions runner (act_runner) on THIS host for tlam89/sciagent.
+# Target: the Gitea + app box 103.149.170.102 (run this ON that box, as root).
+#
+# Registers ONE runner with two labels so the CI/CD pipeline can use both:
+#   ci      -> docker mode  (clean ephemeral containers; backend + frontend jobs)
+#   deploy  -> host  mode   (runs on the host so it can drive `docker compose`)
+#
+# Prereqs installed/verified here: Docker + compose plugin, Node.js (needed by
+# host-mode actions/checkout). Re-runnable: skips steps already done.
+#
+# Usage (token already minted for this repo; rotate via Gitea if it expires):
+#   sudo bash setup-gitea-runner.sh
+# Override:
+#   GITEA_URL=http://localhost:3000 RUNNER_TOKEN=xxx bash setup-gitea-runner.sh
+# ============================================================================
