Vanilla JS and SASS

Tons of hidden challenges here. I had to jump through some hoops to get all the APIs working correctly. I made a quick proxy API for the world time on Heroku (to get it working over HTTPS), which is why the initial load might take a while (the API app goes asleep after some inactivity).

A tiny nitpick bug I never managed to solve is the ":" between hours and minutes get pushed to the bottom when I set a negative letter-spacing. Not on Firefox, however.

Focused mostly on practicing JS and animations on this one, but any feedback is welcome!
