hello_world.cpp

// Copyright 2026 Sebastiano Merlino
// libhttpserver hello-world example — the lambda form.
// Compiles in ten lines including main(), with no http_resource subclass
// and no raw-pointer ownership. Production code typically qualifies names
// explicitly; the `using namespace` here is a one-off so this file can
// document the shortest possible end-to-end demo. See shared_state.cpp
// for the class-based pattern that is appropriate when handlers must
// share mutable state.
