 *  Describe Azure infrastructure as strongly typed C++23. Compile it.     *

 *  If it compiles, it deploys:                                            *
 *    - invalid resource names ............ compile error                  *
 *    - missing required properties ....... compile error                  *
 *    - hard-coded secrets ................ compile error                  *
 *    - dependsOn ......................... inferred, never written        *

// examples/demo/main.cpp — the §4 IaCpp demo (T204/T205 final form).
//
// Reads like Bicep, compiles like C++. Running this binary emits a valid ARM
// deployment template to stdout; pipe to az deployment group create to deploy.
//
// Fidelity note (vs §4): the storage account name is LOWERCASE
// ("iacppdemo001"). The §4 prose shows "IaCppdemo001", but that violates the
// lowercase-only rule the AccountName consteval type now enforces — lowercase
// is the correct, compiling form.
