The sample app we're using for this site can be found here: https://github.com/xjamundx/egghead-rtkq

It's a website for dog grooming that has a few important features:

• Seeing a list of services loaded from an API
• Filtering that list based on your list of dogs
• Adding and removing dogs from your list
• Sending a message via the contact form

The app itself is powered by https://vitest.dev/ and https://mswjs.io/.
