+# code-server image — VS Code in the browser for apk8s.
+#
+# Extends the upstream codercom/code-server with:
+#   - gh CLI for GitHub operations from the integrated terminal
+#   - tmux for persistent terminal sessions
+#   - claude (Claude Code) and codex for integrated AI assistance
+#   - entrypoint that configures git identity + gh auth from env vars on boot
+#
+# Deployed at code-server.prodromou.com via WARP private routing
+# (envoy-internal gateway, WOVED-35).
