Pizza Slice Party Splitter

revealed

You're hosting a pizza night and everyone ordered different sizes. Build a single-page app that helps a group figure out how to split pizza slices fairly.

**What to build:**
- Let the user enter the number of pizzas, slices per pizza, and number of people eating
- Calculate how many slices each person gets (whole number) and how many leftover slices remain
- Show a visual breakdown: a simple grid or row of pizza slice icons (🍕) grouped by person, color-coded so each person's slices are distinct
- Allow the user to reset and try different combinations instantly

The app should feel fun and immediate — enter three numbers, see the split visualized on screen with no page reloads. Keep it to one screen with no backend needed.

Problem Solving & Design B

The layout is responsive and well-structured, but interactive elements lack visible focus indicators and hover/active states beyond the reset button.

Completeness B

Core split calculation, visual distribution, and reset all work end-to-end, but the app has no empty or loading states and no error surfacing beyond inline validation text.

Technical Craft A

The codebase is cleanly modularised with explicit TypeScript interfaces, named pure functions, a comprehensive Vitest suite, and intentional motion with reduced-motion support.
