Let's begin by reviewing our objective for this micro-quest.

Objective: In your own words, write a short paragraph defining what a Pull Request (PR) is and explaining its primary purpose in a collaborative software development workflow.

Next, we'll perform initial verification steps to understand the current state and confirm the specification we need to meet.
