FamilyNido — a self-hosted PWA for a single household: shared calendar, chores, meals, school agenda, health records and a family wall. One instance per family, deployable with `docker compose` on any home server. Stack: .NET 10 (ASP.NET Core Minimal APIs) + EF Core 10 + PostgreSQL 16 on the backend, Angular 21 (standalone, signals, zoneless) + Tailwind CSS v4 on the frontend, SignalR for realtime, optional OIDC alongside local credentials, integration via a versioned `/api/v1/**` public API. See README.md for the module overview and how to deploy.
