// This is a utility class containing reusable helper functions used throughout the app.
//
// The getItemIcon method returns the appropriate emoji icon for each item type.
//
// The getTypeColor method assigns consistent colors to tabs, bookmarks, and history items.
//
// The getItemStats method calculates how many items of each type exist in a list.
//
// The filterItems method filters a list based on search query and filter type selection.
//
// The sortItems method sorts items by different criteria like recent, title, url, or visit count.
//
// All methods are static so they can be called without creating an instance of the class.
//
// This keeps common logic in one place rather than duplicating it across multiple files.
