Why this matters
You just changed the page by editing your browser’s copy of it.
In cybersecurity, this is important because a user can modify anything
that lives in the client, like text, buttons, hidden fields, prices,
or values stored in localStorage.
That is a client-side threat vector.
It means the system must not trust the browser for important
decisions.
This site exists to show, in a safe way, how easy it is to tamper with
client-side data and why real security must be enforced on the server.
