Cosmic Pizza 🍕🚀

A tiny, deliberately imperfect Flask app used to demo GitHub Code Quality.

Build a pizza, pick your toppings, and get a price + calorie count. Under the hood the code carries a few small quality and performance issues on purpose, so you can watch Code Quality (CodeQL), code coverage, and Copilot Code Review light them up.

Important

Facilitators: follow DEMO_INSTRUCTIONS.md for a full, step-by-step walkthrough (Modules 0–4).
