Features:

👁️ Hover to reveal — simply mouse over any password or hidden field to see its content
🔒 Eye icon button — appears inside the field; click to pin visibility (stays revealed even when you move the mouse)
⚙️ Popup settings panel — toggle hover reveal and eye icon independently, or disable the whole extension
🔄 Works on dynamic pages — uses a MutationObserver to catch password fields added by SPAs (React, Angular, etc.)
