How is your architecture organized according to Feature-Sliced Design (FSD)? How is the business logic distributed across layers?

In Feature-Sliced Design (FSD) architecture, business logic is distributed across layers, each responsible for its own area:

• App — global settings and application initialization.
• Pages — individual pages that combine functional blocks.
• Features — specific functionalities, such as authorization or search.
• Entities — business entities with logic and state, such as a user or product.
• Shared — reusable components, utilities, and styles.

Business logic is concentrated in the Entities and Features layers. Entities are responsible for managing the state and rules of specific entities, while Features implement user scenarios by combining Entities and Shared. This approach allows for easy scaling of the application and maintaining clean code.
