Sidekick: Customize Checkout Page Layout

Help me customize my Shopify checkout page layout:

Store name: [YOUR STORE NAME]
Current checkout issues: [DESCRIBE ANY PROBLEMS OR FRICTION POINTS]
Brand style: [MINIMAL / MODERN / CLASSIC / BOLD]
Primary brand color: [HEX CODE OR COLOR NAME]

Please help me with the following checkout customizations:


  
    Header area - Add my store logo centered at the top, with a clean background that matches my brand. Remove any unnecessary navigation links that distract from completing the purchase.
  
  
    Progress indicator - Configure a clear step-by-step progress bar showing Information, Shipping, and Payment stages so customers always know where they are.
  
  
    Form field layout - Arrange the customer information fields in a logical order. Group related fields together (name fields on one row, address fields grouped). Remove any optional fields that are not needed for my business.
  
  
    Order summary panel - Make the order summary sidebar sticky on desktop so it stays visible as customers scroll. Show product thumbnails, quantities, and a running total at all times.
  
  
    Mobile optimization - Ensure the checkout is fully responsive. On mobile, place the order summary in a collapsible section at the top so customers can review their cart without scrolling.
  
  
    Typography and spacing - Match the checkout fonts to my storefront. Use adequate spacing between form sections so the page feels clean and not cramped.
  


Give me the specific Shopify checkout settings to change and any Liquid or CSS customizations needed.
