/**
 * A data class representing the UI state for displaying notes in the app.
 * This class is used to encapsulate the state of the UI in a single immutable object. 
 * The immutable nature of the state guarantees that each update leads to a predictable
 * UI change, helping prevent bugs and ensuring smooth interactions.
 *
 * @param isLoading Indicates whether the UI is currently in a loading state.
 * @param notes A list of notes to display in the UI. Defaults to an empty list.
