Make it a Javascript (just put into Favorites an icon that links to javascript:(function(){...})() which creates and inserts a script block into the currently open site (Yale site in this case) which loads the big .js from a server. Users browse the regular Yale page, click on their icon in the Favorites bar and the page extends so it can look and perform however you want it to look and perform - unblockable!

GreaseMonkey and Scriptish userscripts are run in the Chrome plugin TamperMonkey https://chrome.google.com/webstore/detail/tampermonkey/dhdgf...

Or better yet, do a desktop app.
