The game is built using HTML, CSS, and JavaScript with no external dependencies, making it lightweight and fast. Key technical aspects include:

1. Dynamic Word Shuffling

• Words are scrambled using the Fisher-Yates shuffle algorithm.
• Original word indices are tracked to verify correctness.

function shuffleArray(array) {
    for (let i = array.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [array[i], array[j]] = [array[j], array[i]];
    }
    return array;
}

2. Game State Management

• Tracks:
• Current stage
• Selected words
• Score
• Time remaining
• Resets properly when restarting.

3. Responsive Design

• Works on mobile and desktop.
• Adapts to different screen sizes.

4. Dark/Light Mode Toggle

    --text-color: #e8eaed;
    --card-color: #303134;
}

5. Progress Tracking
