One-page minimalist checkout flow (remove extra steps/fields)

The user suggests a more minimalist payment flow to reduce friction and increase conversion. Specifically: 1. Place the payment form (card number, expiry, CVC) directly on the first page to remove the "Continue to payment" button step. 2. Remove the "Full Name" field or make it optional/pre-filled from account info. This aligns with modern minimalist payment UX like Stripe's design.
