3. Next Steps

1. Confirm design tweaks: color palette, custom layouts (e.g., 2×2 vs. 4×4 grids).
2. Prioritize modules—would you like to start with:
   • Database schema & API endpoints (products, pincodes, taxes)
   • Authentication & payment gateway integration
   • Frontend component library & theming
3. Share brand assets (logos, fonts, primary/secondary colors) for a refined mock-up.
