💡 What This App Does

This is a small web app that checks how strong your password is.
As you type your password, a colorful progress bar shows the strength:

• 🔴 Weak (e.g. only letters or short length)

• 🟠 Medium (mix of letters and numbers)

• 🟢 Strong (letters, numbers, symbols, and good length)
