.NET project in solution

`Pams.Business` is a .NET project within the Pams solution. It contains business-layer logic that coordinates application workflows between higher-level consumers and underlying data or service components.

## Usage

```ts
// Call an API endpoint backed by Pams.Business business logic.
const response = await fetch("/api/pams/items", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    name: "Example item",
  }),
});

if (!response.ok) {
  throw new Error("Request failed");
}

const item = await response.json();
console.log(item);
```

## AI Coding Instructions

- Keep business workflow logic in `Pams.Business`; keep transport-specific concerns in API or UI projects.
- Define clear request and response models at module boundaries rather than exposing persistence entities directly.
- Route database access and external calls through referenced data or service abstractions.
- Preserve existing project references and dependency injection patterns when adding business services.
- Add validation and domain-rule checks before invoking data access operations.
