You can open DevTools to set the Karma coffee cup to a more interesting GIF (only works on Chrome):

setInterval(() => document.querySelector("h1 > svg")?.parentElement?.setHTML("<img src='http://127.0.0.1:8000/references/assets/this-is-fine.gif'/>"), 100)

Description

Simulating a simple Minecraft emerald bank alerting service that alerts when the balance reaches $0 (EMERALDS_NO_ENOUGH).

Everytime the bank is queried, it reads from balance.txt, minuses from expenses.txt and adds from income.txt.

A benign alert, JARYL_IS_DUMB_DUMB, pops up after 2 minutes of the service being up.
