Build me a full web app for South Asian Fitness, a nutrition and fitness planner made for Desi food and habits. I want users to sign up with email or Google, set their goals, food preferences, allergies, budget, and get personalized meal plans that understand real cooking, like oil, ghee, tarka, paratha, biryani, roti, daal, and karahi.

The app should show calories, protein, carbs, and daily progress in a clean dashboard, plus onboarding, meal planning, progress tracking, and account pages. It should also have AI powered meal and workout help, with streaming meal plan generation and structured results. Make sure the app uses a dark modern look with amber accents, and includes login reliability for slow backend startup.

I also want the backend and frontend wired together, with a PostgreSQL database, migrations, and local development setup. If you need to check current docs online for anything, feel free to do that.
