Responsive Reservation Form Demo

Open index.html in a browser. The example uses semantic HTML, responsive CSS, and vanilla JavaScript date checks and a local-only confirmation message. It does not submit information to a server or create a reservation.

Files:
- index.html: accessible reservation form markup
- styles.css: responsive layout and form styling
- script.js: date validation and demo confirmation

To connect a real reservation workflow, add a secure backend or booking provider and its privacy, validation, and data-handling requirements. Do not treat this demo as a real booking system.
