"""Regression test for the CORS-preflight auth bypass.
AuthMiddleware runs outside CORSMiddleware, so it used to 401 the credential-less
OPTIONS preflight before CORS could answer it -- which blocks every cross-origin
browser/WebView client before the real request is ever sent. The fix lets a
genuine preflight through; `is_cors_preflight` is the pure predicate it uses.
Guard it so the bypass can't silently regress.
