The backend requires an API key, which would be exposed if the client called it directly.
Routed all backend calls through Next.js API routes that add the key on the server.

Challenges & solutions
The technical problems our team solved to ship a reliable, unified mobile experience.
Moving a signed-in user from the browser to the native app securely.
Implemented OAuth 2.0 with PKCE and a universal-link callback, so tokens are never passed in plain URLs.
The default Stripe Checkout did not match the minimal brand design.
Used the embedded Stripe Payment Element with custom styling, lazily loading Stripe only on the payment step.
The same calm, animated feel had to work in a browser.
Rebuilt the background in Three.js and the hold gesture as a reusable useHoldToEnter hook driven by requestAnimationFrame.
Coordinate identities must be unique and must never change after creation.
Added client-side validation rules plus server-side checks, and locked the coordinate fields after the account is established.
