// Migrated from https://en.wikipedia.org/wiki/User:Garzfoth/common.js on 2021-05-04

// Notes:

// • Variable naming: I believe I stripped the dollar sign prefixes for readability. IIRC they were only in use as an informal way to denote jQuery variables, and I believe they were being misused for sloppy variable declaration as well...

// • Major changes: Wrapped mw.util.addCSS() inside mw.loader expression
