I am working on a Next.js 15 project and aiming to achieve perfect site responsiveness across all devices and browsers. The main goals are:

Ensuring all components scale properly based on screen size, including handling layout shifts and dynamic spacing.
Dynamically rendering different components based on viewport size or browser type.
Handling server-side and client-side rendering issues when detecting screen size.
Managing spacing, padding, and layout adjustments dynamically for different devices.
