enisocyberguards-collab/eniso-cyberguards ? reverse-engineered prompt

Build me a small recruitment website for ENISo CyberGuards with two steps.

The homepage should welcome people and include a mini challenge where they have to decode a hex string, then enter the SHA 256 hash to unlock the rest of the site. If they solve it, give them access to a protected application page. If not, they should not be able to reach it directly by typing the URL.

On the application page, I want a simple form with name, email, program or major, and a motivation message. When the form is submitted, send the answers to a Google Sheet. Make the protection server side, with a secure cookie so it cannot be bypassed from the browser.

Use a clean modern design, mobile friendly, and keep the logic in TypeScript. If you need current docs for anything, look them up online first.
