### This is a base component. It should not be used in your feature code directly but as a "base" for other UI components

# HeaderBase

The `HeaderBase` component is a reusable UI component for displaying a header with optional startAccessory, children (title) and endAccessory content areas. It is designed to be flexible and customizable for various use cases to keep a visually balanced appearance.
