Made for print, or by a cousin, or never really made at all. This tier draws the mark first, then builds the motion into it — which is the only order that works.

One mark, animated. Not a family of marks, and not rules for how the rest of your site should move. That is Tier III.
Sketches, a name, brands you admire. A blank page is genuinely fine here.
