/* TODO: ...
    - Header menu's background not appearing when linked via anchor tag. Requires at least one scroll action atm.
 
    Aesthetics:
    - fix font-weights
    - Animate "EXE.RCISE | ESICR.EXE" as Exercise expanding right then reflection words. Animate like, a bar scan, for example. Then make pop and scale larger
    - black box background behind brand/logo across website to pop. Make clickable on some.
        - appear/disappear
 
 
    More:
    - can't click logo - competing w/ header-right's z-index
    - ^ couldn't a solution be just put some transparent clickable thing over it?
