Checkout Page- Standard Two Column
A balanced two-column checkout layout with the form flow on the left and a persistent order summary on the right. Maintains constant cost visibility while users complete required steps. Familiar, low-cognitive-load structure. Best suited for General eCommerce, DTC brands, multi-item carts, users already comfortable with online checkout.

Summary
Create a professional grayscale e-commerce checkout interface using a 58/42 split-screen layout. Focus on high-contrast legibility, structured form fields, and a clear information hierarchy. The design should prioritize flow with a secondary sticky order summary column and a clean, sans-serif typographic system.
Style
The style is a 'clean wireframe' aesthetic using the 'Public Sans' typeface (weights 400, 500, 600). The color palette is strictly grayscale: White (#FFFFFF), Ghost White (#F9FAFB) for surfaces, Light Gray (#E5E7EB) for borders, and Jet Black (#111827) for primary actions. Transitions are subtle (150ms ease), and focus states use a soft ring effect (#9CA3AF).
Layout & Structure
A two-column responsive layout. On desktop, the left column (58% width) handles form entries (Contact, Shipping, Payment) and the right column (42% width) provides a sticky order summary with a light gray background. On mobile, the order summary moves to the top and is collapsible.
