//! Shared infrastructure for projects spawned from `rust-template`.
//!
//! This crate extracts the generic plumbing (config loading, logging,
//! health checks, metrics, OpenAPI, OIDC auth, systemd integration) so
//! downstream projects consume it as a git dependency and receive
//! improvements via `cargo update`.
//!
//! # Feature flags
//!
//! - **`cli`** — `CommonConfigFile` (file side of the CLI/file merge),
//!   CLI logging, `CliApp` trait, the `MergeConfig` derive (which
//!   generates `CliRaw` with per-app-prefixed env vars), and
//!   `#[foundation_main]`.
//! - **`server`** — Health registry, metrics endpoint, OpenAPI/Scalar
//!   helpers, SPA fallback, systemd notify/watchdog, server logging.
//! - **`auth`** (implies `server` + `cli`) — OIDC login/callback/logout
//!   handlers, `require_auth` middleware, `Server` runner, `ServerApp`
//!   trait, and `BaseServerState`.
