A trait that adds magic property accessors (__get, __set) and explicit getters/setters for arbitrary attributes. It is self-contained, can be used in any PHP class to provide dynamic attribute storage, and demonstrates clean implementation of the 'magic property' pattern with proper separation of setAttribute, getAttribute, setAttributes, getAttributes methods.

A trait that adds a consent callback mechanism. It stores a Closure, checks existence, and invokes it via Laravel's App::call, which resolves dependencies from the container. This pattern is reusable for any scenario where a deferred callback with dependency injection is needed, not just cookies. The trait is isolated and demonstrates a clean way to handle callbacks with Laravel's IoC.

A trait that manages a collection of Cookie or CookiesGroup instances. It provides methods to add individual cookies (via instance or Closure), retrieve all cookies as a flat array, and retrieve raw defined items. The trait is self-contained and could be extracted to manage any collection of similar objects. It demonstrates a clean pattern for aggregating items with different types (single vs group) and flattening.

A class that represents the result of a consent callback. It collects cookies (via Laravel's CookieFacade) and script tags to be added to the response. It is used by the HasConsentCallback trait to build the output. The class is self-contained, demonstrates a clean builder pattern for assembling response items, and is reusable in any consent-like scenario.
