Global theme elements?

I have customized the main/home page of a farmers’ market website using the Panino Upfront theme. There are some obvious changes but just one example to use, I changed the “Panino” text in the header and adjusted the position of both that text and the menu.

The menu links mostly jump to different sections of the page. The “Blog” link goes to a separate page as does the “terms & privacy” in the footer. These pages, or when creatinga new page, don’t retain the changes made. I tried to set the header as a global element but I think that applies to the block and not the text & menu objects.

Is there a way to apply these changes to any existing pages or new pages?
