Given I am on https://www.performance.gov/cx/executive-order/ When I scroll Then I see the changes Amira requested

Adapt topper layout from CX HISPs

• [x] Reuse layout from "above the fold" section from CX HISPs (contained in the HTML tags in the image)
• [x] Set hero image to Biden signing EO
• [x] Set title
• [ ] Set first item in Table of Contents

Accordions

• [ ] In each accordion, add new content from Word doc

Modify "What the American people should expect of their government"

• [ ] Delete stats content from (we just want to preserve the checklist)
