Structure and UX
The quiet logic underneath.

RION is the lead. When a layout seems obvious in hindsight, that is RION's work: the structure you never had to think about.
Structure is the part nobody compliments and everybody feels. RION decides what belongs on a page, in what order, and what has to be removed so the order reads. It arrives last in the sequence because the others stand on it, and because a reveal has to be earned.
It works but nobody can use it.
That is the test each of the five has to pass. Take one out and something specific breaks, and it is never the same thing twice.
RION draws the order the other four stand on, and FORJA is the one who has to hold it up under real conditions. The two of them decide between them whether a page is finished.
RION removes what is not doing work, which is usually the fastest way to make VEKTOR's one ask visible. Most conversion problems turn out to be structure problems wearing a different coat.
Obvious in hindsight is the whole objective.
