//! ## Components
//!
//! - `config` — Shared configuration store (routes, TLS certs, upstreams, policies)
//! - `server` — Pingora server lifecycle and proxy bridge
//! - `tls` — TLS termination via rustls with SNI-based certificate selection
//! - `load_balancer` — Upstream selection algorithms
//! - `health_checker` — Active and passive upstream health checks
//! - `filters` — Request/response filter chain (real IP, headers, rate limit, sticky, WS)
//! - `observability` — Prometheus metrics and OTLP tracing
//! - `hot_reload` — Graceful config reload without dropping connections
