The entrypoint for defining your web interface, such as controllers, components, channels, and so on.

This can be used in your application as:

use LiveviewPlaygroundWeb, :controller
use LiveviewPlaygroundWeb, :html

The definitions below will be executed for every controller, component, etc, so keep them short and clean, focused on imports, uses and aliases.

Do NOT define functions inside the quoted expressions below. Instead, define additional modules and import those modules here.
