Fix Resume Download Bugs

My in-house team has stepped away from koyosuit.com and the resume builder is now stuck at the very last step. Users can upload their details and preview the template, but the moment they click to download the final file the flow breaks. I need someone who has already walked through https://koyosuit.com/builder/upload?type=free, seen the issue first-hand, and is ready to talk specifics rather than theory.

Here’s what I expect:
• You replicate the full builder journey yourself, pinpoint every gap that prevents the file from reaching the user, and give me a concise report of those findings.
• You then patch the code so the download button reliably delivers the finished resume (PDF, DOCX and any other format currently offered by the app), cleanly populated with the data entered in the builder.
• After the fix, you run end-to-end tests on the live domain to confirm the file saves correctly across modern browsers.

Hand me the brief gap analysis, the updated source, and proof the downloads now work. Once that’s done, I’m happy to move on to any additional refinements you spot along the way.
