Ok, this is doing my head in, which takes increasingly less effort to do as I get older

You can apply set styles in two ways:
1) Text Object > Text > Predefined Style > Style (field)
2) Text within an Object - Highlight the text - right click - set style
A) I'm deploying Text within each "slide" of a Carousel and using a text shadow to make the text stand out from the BG image of each "slide" - that works well
B) I defined two Carousel text styles - one for the title and another for the text below.
C) I assigned the respective style using set style 1) above.
D) I then added break points for each style.
E) But I can only get the text to "observe" the BP setting by using set style 2) above.
