This need a lot more scary quotes around modern and tooling.
The JS "ecosystem" is a cancer: nowadays when you want to do some front-end work with some CSS you usually end with an install of node and npm/webpack/the-shit-du-jour, half of them crying about incompatibilities and how you should use the shit-du-lendemain instead to compile you don't really don't know what, it still takes 20mn to see the result. All you wanted was to edit some CSS. And surprise: now half of your other projects won't build anymore because you had to install npm-1.911-HELP-ME-DAD and the option to not install globally changed from -not-everywhere to --just-a-local-beer.
