An EMPTY empty page

Is there a way to create a page with an empty template build (no unnecessary js or css links etc)?

With a third-party plugin I’m creating a page with a full screen Google map with all of our customers on it. There are nearly a thousand customers and each customer has a tiny logo as marker, so it’s important that I minimise page load speed wherever possible. As there is no header, footer, menu, page text/links/…, and so on, there’s really no reason to insert all of the js and css etc.

I’ve already selected the “Blank” template to the page.
