Initial setup: OpenResto deployment for Lunkaberg breakfast booking

Adapts upstream's release docker-compose.yml to run behind this server's
Nginx Proxy Manager on the shared my-main-net network instead of publishing
host ports. Includes docs/ for session continuity.

+# State — Lunkaberg Frukost (OpenResto)
+
+## What this is
+Client project for lunkaberg.se — a breakfast booking service, built on
+[OpenResto](https://get.openres.to) (open source, MIT), self-hosted at
+`frukost.lunkaberg.se`.
+
+## Stack
+- OpenResto v2.2.0, official pre-built images (`ghcr.io/karanshukla/openresto-*`)
+- Backend: ASP.NET Core 10 + SQLite (in `db_data` volume)
+- Frontend: React (Expo/React Native web build)
+- Reverse proxy: bundled nginx container (`lunkaberg-reverse-proxy`), fronted
+  by this server's Nginx Proxy Manager — no host ports published, everything
+  rides the shared `my-main-net` Docker network like the other app projects
+  on this box.
+- Location: `/var/www/lunkaberg/`
+- Git: tracked, remote at `https://gitea.axbom.com/root/LunkabergB.git`
+  (this is a client project, so — unlike most of Per's hobby projects —
+  it's using real version control instead of live-editing.)
+
+## Status as of 2026-09-21
+- [x] Project directory created, git initialized, Gitea remote added
+- [x] docker-compose.yml adapted from upstream release for the my-main-net /
+      NPM pattern (no host port conflicts with NPM's own 80/443)
+- [x] .env created with generated JWT_KEY and admin password (not committed —
+      see .env.example for the template)
+- [ ] `docker compose up -d` — pulling images / bringing the stack up
+- [ ] DNS: A record for frukost.lunkaberg.se → 64.112.127.212 (Per manages
+      lunkaberg.se DNS himself)
+- [ ] NPM proxy host for frukost.lunkaberg.se → lunkaberg-reverse-proxy:80
+- [ ] First login / admin dashboard walkthrough
+- [ ] Decide: SMTP for booking confirmation emails (needs a mailbox at
+      lunkaberg.se, separate from Per's personal Migadu setup)
+- [ ] Decide: push notifications (VAPID), Apple/Google Wallet passes —
+      left disabled for now, app degrades gracefully without them
+
+## Known issues / watch items
+- Server disk was at 87% (6.5GB free) before pulling OpenResto images —
+  keep an eye on `df -h` after this and future installs.
