Overview

Thin wrapper over HTTPX. Returns a plain result struct so callers/tests never touch HTTPX response objects directly. Note: HTTPX does NOT follow redirects unless the :follow_redirects plugin is enabled, so we intentionally leave it disabled so a 3xx to an internal URL can't bypass SSRF checks.
