Conventions in these recipes

• Every recipe assumes composer require initphp/socket has run and the vendor/autoload.php is loaded.
• Loopback (127.0.0.1) is used for everything that needs a host so the snippets run unmodified.
• TLS recipes generate self-signed material to keep the snippets self-contained. Do not ship that — see SSL Context Options for production-grade configuration.
• The recipes prefer live() for the canonical pattern. To embed them in your own event loop, swap live() for a while (… $server->tick(…)) { … } shape — see Event Loop Integration.
