/**
This userscript is based predominantly on https://greasyfork.org/en/scripts/458501-vector-layout-for-wikipedia/code, as well as https://gitlab.com/userscripts3/Invidious-Preferences-Userscript.
It is designed to redirect wikipedia pages using the modern (2022) design to pages using a more classic design.
By default, it redirects to a theme based on Wikipedia's appearence in 2008 (modern). Other themes are avalible based on designs from 2002 (cologneblue), 2010 (vector), etc. For more information, see https://en.wikipedia.org/wiki/Wikipedia:Skin
To edit the enforced theme, change the skinchoice below. */

/**Anytime you load a wikipedia page, this script will check the URL for the desired parameters, and apply them if not found. */
