An empty SBT project with dependencies on Cats and Cats Effect.

This repository holds the Nu Pet Cat project 🐱, a digital pet used as a learning tool. Its primary purpose is to demonstrate the GitHub workflow (like Branches, Pull Requests, and Issues) to non-technical teams, providing a safe sandbox for collaboration.

SkillCrush 102, lesson 05, task 04: A Code Sandbox project that displays a cat profile and updates when parts of the UI are hovered over, part 2 - the theme can now be changed between dark and light
