Layout of the mockup using the Next.js framework

The layout is implemented using the Next.js framework — a modern solution based on React, which provides a flexible component architecture, optimized server-side rendering, increasing productivity and loading speed. Thanks to built-in routing, plan pages and order forms are easily scalable and manageable without additional libraries. The interface is structured as separate UI components, making code reuse and maintenance easier. For styling, Tailwind CSS or another utility-first CSS system is likely used, allowing quick adaptation of the design to different screens and user needs.
