 The Problem With Anemic Domain Models
-------------------------------------

Most Laravel codebases pass raw arrays or plain Eloquent models between layers. This works until it doesn't: you find yourself writing `$data['email']` in five controllers, validating the same format in three places, and debugging a `null` that should never have been allowed in.

Domain-driven design offers two lightweight tools that fix this without requiring a framework: **value objects** and **DTOs**. PHP 8.3 readonly classes make both feel native.

Value Objects: Identity Through Value
-------------------------------------

A value object has no identity beyond its data. Two `Money` instances with the same amount and currency are equal. They are immutable by definition.
