// This is our data model that represents a single tab, bookmark, or history item.
//
// It holds all the information we need about each item: title, URL, favicon, when it was accessed, etc.
//
// Think of it as a blueprint or template for storing browser item information.
//
// Every tab, bookmark, or history entry in our app is stored as a TabData object.
//
// The constructor creates new TabData objects with required fields like id, title, and url.
//
// Optional fields have default values, like favicon defaults to empty string and isPinned defaults to false.
//
// The fromJson factory method converts JSON data from the browser API into a TabData object.
//
// It handles different date field names from different sources like lastAccessed, lastVisitTime, dateAdded, or timestamp.
//
// It also handles missing data gracefully by using default values with the ?? operator.
//
// This class is the foundation of our app since everything revolves around displaying and managing these items.
