// Step 1890: poly-api test project spec — Go http-server + TypeScript api-client
//
//  t1: PolyApiProject::make() produces correct project name and structure
//  t2: http-server section features match expected values
//  t3: api-client section features match expected values
//  t4: interface is from api-client to http-server
//  t5: after routing, http-server → Go and api-client → TypeScript
