Caddyfile

+# Reverse proxy template for a REAL deployment (real domain + automatic HTTPS).
+# Not needed for local testing against localhost:4650 — this is the step you
+# take once you're actually putting this in front of a public domain.
+#
+# Usage:
+#   1. Point 3 DNS records at this machine: your app domain, your api
+#      subdomain, and your cdn subdomain (matching FRONTEND_URL / APP_URL /
+#      S3_PUBLIC_URL in apps/api/.env and VITE_APP_URL / VITE_API_URL in
+#      apps/web/.env).
+#   2. Install Caddy (https://caddyserver.com/docs/install) directly on this
+#      host — it is NOT part of docker-compose.yml, so it binds host ports
+#      80/443 directly and reverse-proxies to the containers' published
+#      ports below.
+#   3. Copy this file to /etc/caddy/Caddyfile (or wherever your install
+#      expects it), filling in the three domains.
+#   4. sudo systemctl reload caddy   (or: caddy run --config Caddyfile)
+#
+# Caddy issues and renews Let's Encrypt certificates automatically the first
+# time each domain is requested — no manual cert steps needed.

+## 9. (Optional) Put a real domain + HTTPS in front
+
+For actually deploying this somewhere reachable, use the `Caddyfile` at the repo root
+as a template. It's a standalone Caddy install on the host (not part of
+`docker-compose.yml`) that reverse-proxies 3 domains to the 3 ports already published
+above (`:4650`, `:3024`, `:3900`) and handles Let's Encrypt certificates automatically.
+See the comments at the top of `Caddyfile` for exact steps. Not needed for local
+`localhost:4650` testing — skip this until you're pointing a real domain at the
+machine.
