Root cause found: winscp.net's download URL serves a human "please wait" landing page (18KB HTML) instead of redirecting to the real file, unless the User-Agent contains a known download-tool signature like curl or Wget. PowerShell's own default UA always gets the landing page - confirmed by reproducing locally with various UAs against the live URL. Not antivirus, not TLS, not a network block; overriding -UserAgent to a curl string on Invoke-WebRequest resolves it.
