+title: Public Caddy Route for Lombard Dashboard
+status: backlog
+priority: P1
+effort: S
+depends_on: []
+tags: [ops, deploy, routing]
+summary: Move the production route to public HTTPS at lombard.uncloud.tech.
+acceptance_criteria:
+  - Caddy proxies lombard.uncloud.tech to the deployment container.
+  - HTTPS works with a valid certificate.
+  - Health check succeeds through Caddy.
+  - Deployment docs note that vd1.uncloud.vpn was retired in favor of the public route.
+technical_notes:
+  - Keep public-exposure controls aligned with SEC-001 Turnstile bootstrap protection.
