A 30-second WPM + accuracy test built with vibecoding in ~8 minutes.
Build a typing speed test in React with: - Pick from a set of sample paragraphs - 30-second countdown timer that starts on first keystroke - Live WPM and accuracy calculation (5 chars = 1 word, count only correct chars) - Character-by-character highlighting: correct = green, wrong = red, upcoming = gray - Restart button and "new text" button - Dark UI, no external dependencies
