Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Denial of Service: Development servers running httpbin can hang indefinitely when processing chunked transfer encoding requests if the WSGI environment is not configured to handle them. A guard was required in the global pre-request handler to reject these payloads.

Denial of Service: The lack of boundary checks on numeric parameters in response-delaying endpoints like `/drip` leads to division-by-zero crashes or unconstrained delays that exhaust thread pools and server capacity.

Information Disclosure: Deploying the application with Flask's interactive debugger active allows remote attackers to obtain sensitive system variables or execute arbitrary code via the interactive console upon throwing an error.
