// Package hws provides a lightweight HTTP web server framework built on top of Go's standard library.
//
// HWS (H Web Server) is an opinionated framework that leverages Go 1.22+ routing patterns
// with built-in middleware, structured error handling, and production-ready defaults. It
// integrates seamlessly with other golib packages like hlog for logging and hwsauth for
// authentication.
//
// # Basic Usage
//
// Create a server with environment-based configuration:
//
// cfg, err := hws.ConfigFromEnv()
// if err != nil {
// log.Fatal(err)
// }
//
// server, err := hws.NewServer(cfg)
// if err != nil {
// log.Fatal(err)
// }
//
// routes := []hws.Route{
// {
// Path: "/",
// Method: hws.MethodGET,
// Handler: http.HandlerFunc(homeHandler),
// },
// }
//
// server.AddRoutes(routes...)
// server.AddMiddleware()
//
// ctx := context.Background()
// server.Start(ctx)
//
// <-server.Ready()
//
// # Configuration
//
// HWS can be configured via environment variables using ConfigFromEnv:
//
// HWS_HOST=127.0.0.1 # Host to listen on (default: 127.0.0.1)
// HWS_PORT=3000 # Port to listen on (default: 3000)
// HWS_GZIP=false # Enable GZIP compression (default: false)
// HWS_READ_HEADER_TIMEOUT=2 # Header read timeout in seconds (default: 2)
// HWS_WRITE_TIMEOUT=10 # Write timeout in seconds (default: 10)
// HWS_IDLE_TIMEOUT=120 # Idle connection timeout in seconds (default: 120)
//
// Or programmatically:
//
// cfg := &hws.Config{
// Host: "0.0.0.0",
// Port: 8080,
// GZIP: true,
// ReadHeaderTimeout: 5 * time.Second,
// WriteTimeout: 15 * time.Second,
// IdleTimeout: 120 * time.Second,
// }
//
// # Routing
//
// HWS uses Go 1.22+ routing patterns with method-specific handlers:
//
// routes := []hws.Route{
// {
// Path: "/users/{id}",
// Method: hws.MethodGET,
// Handler: http.HandlerFunc(getUser),
// },
// {
// Path: "/users/{id}",
// Method: hws.MethodPUT,
// Handler: http.HandlerFunc(updateUser),
// },
// }
//
// Path parameters can be accessed using r.PathValue():
//
// func getUser(w http.ResponseWriter, r *http.Request) {
// id := r.PathValue("id")
// // ... handle request
// }
//
// # Middleware
//
// HWS supports middleware with predictable execution order. Built-in middleware includes
// request logging, timing, and GZIP compression:
//
// server.AddMiddleware()
//
// Custom middleware can be added using standard http.Handler wrapping:
//
// server.AddMiddleware(customMiddleware)
//
// # Error Handling
//
// HWS provides structured error handling with customizable error pages:
//
// errorPageFunc := func(w http.ResponseWriter, r *http.Request, status int) {
// w.WriteHeader(status)
// fmt.Fprintf(w, "Error: %d", status)
// }
//
// server.AddErrorPage(errorPageFunc)
//
// # Logging
//
// HWS integrates with hlog for structured logging:
//
// logger, _ := hlog.NewLogger(loggerCfg, os.Stdout)
// server.AddLogger(logger)
//
// The server will automatically log requests, errors, and server lifecycle events.
//
// # Static Files
//
// HWS provides safe static file serving that prevents directory listing:
//
// server.AddStaticFiles("/static", "./public")
//
// # Graceful Shutdown
//
// HWS supports graceful shutdown via context cancellation:
//
// ctx, cancel := context.WithCancel(context.Background())
// defer cancel()
//
// server.Start(ctx)
//
// // Wait for shutdown signal
// sigChan := make(chan os.Signal, 1)
// signal.Notify(sigChan, os.Interrupt, syscall.SIGTERM)
// <-sigChan
//
// // Cancel context to trigger graceful shutdown
// cancel()
//
// # Integration
//
// HWS integrates with:
// - git.haelnorr.com/h/golib/hlog: For structured logging with zerolog
// - git.haelnorr.com/h/golib/hwsauth: For JWT-based authentication
// - git.haelnorr.com/h/golib/jwt: For JWT token management
