/*
Hello epic hacker (maybe skid) you are looking at one of the many scripts that powers the site,
this script has extra comments and info to help you understand what is going on.

This JavaScript code defines functions that manage the state of a web page's tab,
such as its title and icon, and its theme.

It retrieves a JSON object from local storage, which contains the current state of the tab,
and updates the web page's elements with the stored values.

The code provides functions to modify the tab state and settings, such as setTitle, setFavicon,
resetTab, setTheme, and setThemeColor.

These functions update the web page's elements and store the updated state in local storage.
