Sue This is my advice for you:
Sitemap first ā build it as a simple outline/doc, get sign-off before moving on.
Wireframes second ā go page by page, generating low-fi wireframes (structure and content blocks only, no visual design).
Skip Relume/Claude Design ā those tools shine when visual design or a component-based build is needed. Since her dev team is just adding pages to an existing site with no design requirement, going straight to Claude Code keeps it faster and avoids unnecessary tool-hopping.
I hope you are success, if you have any other questions, please drop here. š
