Controlled Greeting Input

Build a name field that greets you as you type and has a button to clear it. You practice controlled inputs and values derived from state.

• The complete interface: the field, the Clear button and the greeting.
• Your job is the logic: store the name, build the greeting and empty the field from the button.
• Keep the aria-label Name, the Clear button and the Hello, ... format of the role="status": the tests use them.

• At the start the greeting is Hello, stranger.
• While you type, the greeting uses what is in the field: with Ana it says Hello, Ana.
• The Clear button empties the field and the greeting goes back to Hello, stranger.

• You open the challenge → you see Hello, stranger.
• You type Ana → you see Hello, Ana.
• You press Clear → the field is empty and you see Hello, stranger.

• Controlled inputs (value + onChange).
• Values derived from state.
