  @moduledoc """
  The `CommunityDemoWeb.Components.FormWrapper` module provides a flexible and customizable form
  wrapper component for Phoenix applications. It offers various options for styling,
  size, and layout to suit different form designs and requirements.

  ### Features:
  - **Customizable Styles:** Choose from multiple color themes, border styles, and design variants.
  - **Layout Flexibility:** Control padding, spacing, and border radius to adjust the form's appearance.
  - **Form Slots:** Define inner content and actions slots to organize form elements and buttons.
  - **Global Attribute Support:** Allows for additional attributes like `autocomplete`, `method`,
  and more to be merged with component defaults.

  This component is ideal for wrapping forms with consistent styles and structure across an application.
