+# =============================================================================
+# Law MCP GHCR Build -- Build Docker image and push to GitHub Container Registry
+# =============================================================================
+#
+# Triggered on push to main and on manual dispatch.
+# Pushes :latest and :sha-XXXXXXX tags.
+#
+# NOTE: This builds the base (free-tier) law MCP image.
+# Premium tools (case law, preparatory works, agency guidance) are injected
+# at build time on the Hetzner prod server via the separate premium build
+# pipeline. The prod server runs LOCAL images (law-mcp-*:latest), not GHCR
+# images -- Watchtower does NOT update law MCPs from GHCR.
+#
+# This GHCR image is used by:
+# - mcp.ansvar.eu (public MCP server)
+# - npm package consumers who prefer Docker over npm
+# =============================================================================
