Storing Objects in Web Storage: The JSON Step

Web Storage is a key-value store with a catch: it only holds strings. To store complex data like a user settings object, you must first serialize it into a string using `JSON.stringify()`. This is how you persist application state or cache data in the browser. The main footgun is forgetting to use `JSON.parse()` when retrieving the data. Your code will receive a string instead of an object, leading to `TypeError`s when you try to access properties that don't exist on a string.
