okay. so what i'm hearing is that HOW the components are ordered is the order they are added to the container (this post was very helpful), BUT i can specifically target them and use flexbox ordering to rearrange as necessary. is that correct? if so, that means CSS specificity should be manageable. awesome! 
to extend this logic a bit, i see the breakpoint container has only two breakpoints. can we override that in a stylesheet and make more? or have i gone too far? we have four different device dimensions to deal with...
