Architecture

Browser → Cloudflare Pages (Astro SSR)
            ↓
         Cloudflare Worker (pes-research-logic)
            ↓
         Main Host (159.89.198.4) via lab.patabuga.co
            ↓
         DO Droplet (152.42.180.225) — ttyd

Health Check Flow

Dashboard poll /api/status via Cloudflare Worker
Worker checks https://lab.patabuga.co/health (main host nginx)
Worker returns VM status to dashboard
