 ## What this stack does
 
-- Runs the core app behind a single public port on `80`.
-- Proxies the UI to the Next.js web app.
-- Proxies REST and websocket traffic to the API service.
+- Assumes Nginx Proxy Manager is the edge proxy and runs on the same Docker network.
+- Keeps `web` and `api` internal to the Docker network instead of publishing host ports.
+- Targets a two-subdomain routing model by default:
+  - `app.<domain>` -> `web:3000`
+  - `api.<domain>` -> `api:4000`
 - Runs ClickHouse, Redis, and NATS JetStream with persistent Docker volumes.
 - Runs the core runtime services: `ingest-options`, `ingest-equities`, `compute`, `candles`, `api`, and `web`.
 - Keeps `replay` opt-in through a Compose profile, because the current replay service starts immediately when the container is enabled.

-Everything else is sent to the Next.js web app.
+The web app should be built with `NEXT_PUBLIC_API_URL=https://api.<domain>` so browser REST and websocket traffic goes straight to the API host through NPM.
 
-That routing matters because the web client falls back to same-host API requests when `NEXT_PUBLIC_API_URL` is unset.
+The API host needs websocket support enabled because the app uses `/ws/*` endpoints for live streams.

 ## Known caveats
 
 - The root `.env.example` still contains a `REPLAY_ENABLED` comment, but the current replay service does not read that variable. Use the Compose replay profile instead.
-- This stack exposes plain HTTP on port `80`. If you want TLS termination on the box, put Caddy, Nginx, Traefik, or a cloud load balancer in front of it, or replace the bundled Nginx config with your preferred HTTPS setup.
+- This stack does not publish `web` or `api` to host ports. NPM must be able to resolve `web` and `api` over the shared Docker network.
 - The stack assumes a single-node VPS deployment. If you later split infra or add external managed services, update the three core connection URLs in `.env`.

+## Smoke checks

+After NPM is wired up:
+
+- `https://app.<domain>/` should load the UI.
+- Browser network requests from the UI should target `https://api.<domain>/...`.
+- Live feeds should connect over `wss://api.<domain>/ws/...`.
+- `docker compose ps` should show no service publishing host port `80`.
