mehranmai/tally-prime-v4.2-enabler-activation ? reverse-engineered prompt

Build me a polished single page website for a Tally Prime 4.2 offline setup and support page.

I want it to feel like a clean product landing page, with a big hero section, a clear download button, and short sections for what it is, how to get started, compatibility, features, and support. Include a simple console style code sample, a profile example, and a comparison table for supported operating systems. Make it look modern and trustworthy, with a strong call to action and good spacing on mobile and desktop.

Please keep everything in one HTML file if possible, and make it easy to open locally or publish on GitHub Pages. Use a professional layout, readable typography, and subtle accent colors. Add small icons or badges where they help. If you need current docs or browser friendly patterns, look them up online.

Also make sure the page clearly explains offline use, local help, and configuration options without feeling cluttered.
