Practical: Build a React SPA Consuming an API

Question

## Problem

Netlify's technical assessment: build a single-page React app that consumes an API endpoint, with error handling and async data flow.

## Example
```
fetch list -> render with loading/error states -> add/filter
```

## Constraints
- General front-end patterns, error handling, async

## What Netlify looks for
Reported Netlify assessment. Clean React patterns, async handling, and debugging approach.
