I've three comments below for you to consider, but other than that I think we're good to merge from my side. Let me know when you're happy to merge.

| ## What is page weight? | ||

| Page weight (also called page size) is the total volume of data—measured in kilobytes (KB) or megabytes (MB)—that a user must download to view a specific webpage. |

Is it worth at least mentioning this as something to look at in future as it gains adoption?
