Start by reviewing the live website’s data and routes, then compare them with the previous visual linked in the issue and the Whimsical site map reference. Create the navigation flow in Figma, using the staging deck and slide 23 for context; it is done when the map accurately reflects the live site and can support the project’s technical documentation.
