Because the exact scope can vary a lot (web‑app, desktop app, API, etc.), could you let me know a bit more about what you have in mind? Below are a few key points that will help me give you a precise, ready‑to‑implement solution:

I’m happy to help you design a solid, reliable feature for a “Tarzan – enlace de descarga normal” (i.e., a normal download link for the Tarzan project).
