Solutions

1. Serve the instinct file with an allowed Content-Type: text/*, markdown, yaml, json, or application/octet-stream.
2. If the server returns HTML (e.g. an error or login page), download the raw file URL instead of a viewer page.

Example fix

# use the raw URL: https://raw.example.com/instinct.md (text/markdown), not an HTML preview page
