How to create an environment-aware configuration in Laravel 11?

I'm working on a Laravel 11 project and I need to set up environment-aware configurations that is accessible with config method. For example, I have a constant.php file in the config directory for general configurations, and a constant.php file in the config/production directory for production-specific configurations.

Here's the directory structure:

config/    constant.phpconfig/production/    constant.php

I want to achieve the following:

config('constant')

On local and staging environments, load only the config/constant.php.

On production environment, load both config/constant.php and config/production/constant.php, with config/production/constant.php overriding any overlapping configurations from config/constant.php.

How can I configure Laravel 11 to achieve this environment-aware configuration loading?

Code samples or any specific methods would be greatly appreciated!

Additional context:

I'm familiar with Laravel's env() function and configuration caching, but I'm not sure how to implement this selective configuration loading based on the environment.
