I want to create btc mining website using PHP, Tailwind Css, Lexend font, and Lucid icons. Make to much modern, attractive and professional UI. User don't want to register, they enter they BTC Wallet addresss only. Make hero page, use grid line background with light visibility. Create each file, css and js both. Don't make heavy animation website, and don't impact on website performance. Make Fully response for mobile also with open and close nav bar with smooth lag free animations.

What the Fuck, you removed my 500+ lines Deep Seek ai agent code? This code want to show in my code editor.

I got error, I tell but didn't make, now make 2x writings speed which have currently. And also write in system propmt give me all in file in html, css and js provide all in one on html. Use internal css and js by they tags. Remember When deepseek writing code then again user try to enter Prompt or trying to send then alerts toast with Please wait for deepseek v3 response. They complete they response and code then again user can write and click on send button. Again remember deepseek v3 OPENROUTER api only provide html code in code editor area not any other instructions and etc. and they don't forget they old code, when some changes then also don't forget past code. Always provide user full complete code.
