  - **Automatic ARIA** - Accessibility attributes managed by the framework

  ## Usage Patterns

  ### Basic Component Usage

      <.button variant="outline" size="lg">
        Large Outline Button
      </.button>

  ### Form Integration

      <.form for={@form} phx-change="validate" phx-submit="save">
        <.form_item>
          <.form_label>Email</.form_label>
          <.form_control>
            <.input field={@form[:email]} type="email" />
          </.form_control>
          <.form_message field={@form[:email]} />
        </.form_item>
      </.form>

  ### Interactive Components with Events

      <.dialog id="user-dialog" on-open={JS.push("dialog_opened")}>
        <.dialog_trigger>
          <.button>Edit Profile</.button>
        </.dialog_trigger>
        <.dialog_content>
          <!-- Dialog content -->
        </.dialog_content>
      </.dialog>

  ### Server-Client Communication

      # Send commands to components from LiveView
      def handle_event("open_dialog", _params, socket) do
        socket = SaladUI.LiveView.send_command(socket, "user-dialog", "open")
        {:noreply, socket}
      end

  ## Customization

  Components support extensive customization through:

  - **Variants** - Pre-defined style variations (e.g., `variant="destructive"`)
  - **Classes** - Custom CSS classes via the `class` attribute
  - **Slots** - Flexible content areas within components
  - **Attributes** - Comprehensive configuration options

  ## Accessibility

  All components include:

  - Proper ARIA attributes and roles
  - Keyboard navigation support
  - Focus management for overlays
  - Screen reader announcements
  - High contrast support

  ## Development

  When extending SaladUI:

  1. **Follow naming conventions** - Use `kebab-case` for data attributes
  2. **Implement state machines** - Define clear states and transitions
  3. **Handle accessibility** - Include ARIA configuration
  4. **Test thoroughly** - Verify keyboard and screen reader usage
  5. **Document examples** - Provide clear usage examples
