(It's sometimes even necessary for every float to live on a
page by itself.) When the float fails to “set”, and waits for the end
of a chapter or of the document, the natural thing to do is to declare
the float as

! modifier has no effect on float page floats; so

containing text as well as one or more float). So, to allow any
size float to take a whole page, set
small, and to ensure that no more than one float occupies a page, make
the separation between floats really big:
