I Built a Searchable HTTP Status Reference With the Exact Spring Way to Return Each

Short summary

HTTP status codes trip up developers deciding what to return mid-controller. This searchable reference shows the exact Spring Boot pattern for each code, clarifies confused pairs like 401 vs 403 and 400 vs 422, and demonstrates when to use ResponseEntity, @ResponseStatus, or ResponseStatusException. Built as single-file HTML with zero dependencies and offline support.
