Urgent Responsive Web3 Button Integration

I need a responsive button integrated on a specific custom-defined page of my Next.js and Tailwind CSS website. The button should either trigger provided JavaScript files or use a standard Web3 connection flow (wagmi + Web3Modal).

Requirements:
- Load scripts correctly in Next.js using next/script
- No hydration errors
- Responsive on desktop and mobile
- Backup of website files before edits

Deliverables:
- Working button on specified page
- Code as PR or zipped files
- Short README with instructions
- Backup of website files before changes & restoration, should you be unable to complete the integration.

REQUIRE VERY FAST WITHIN AN HOUR OR TWO.
