How to set permissions such that users can add, edit, and delete list/library items, but cannot edit web part pages or delete web part pages?

Question

I need the ability for users to add, edit, and delete lists/libraries but not have the ability to edit web part pages or delete web part pages. I am boggled that the Edit Items permission allows for editing and deleting web part pages. The alternative I see at the moment is setting Read permissions across the entire site, and then setting specific permissions on each individual List/Library. The problem with this is that I have site templates, so the security does not remain in the site template (it inherits from the parent). Can someone clarify this for me? Or suggest what permission level I should use to accomplish my goal stated above? Thanks.

Answer 1

Your web part pages could be kept in a single library with specific permissions (all read only) on just that library.

Additionally: Web Part Pages are simply List Items in a Document Library.
