sultansikandar1024-crypto/Email-WhatsApp-Automation-SAAS-Tool — reverse-engineered prompt

Build me AutoBiz AI from scratch as a production ready SaaS for small businesses in Pakistan. I want a polished landing page where owners can start a free trial, sign up with their business name and industry, then use a dashboard to send and manage automated customer messages through email and WhatsApp.

Use the stack from the README, with Next.js, Tailwind, Supabase auth and database, Grok through the Vercel AI SDK, Resend for email, Stripe for card payments, and WhatsApp support for manual JazzCash and EasyPaisa activation. The AI replies should feel local, using a friendly mix of Roman Urdu and English.

Please include login, signup, protected dashboard pages, plan limits for the free tier with 50 messages, billing settings, analytics charts, success and error toasts, and mobile responsive screens. Add basic security like route protection and API rate limiting. Also create clear environment variable setup and deployment notes so I can put it on Vercel.
