The letters ring outwards in parallel lines until the lettering and the pattern are the same thing.

Brand Guidelines
Strokes must alternate: ink / background / ink / background. The number of rings defines the identity's energy. More rings = more dissolution into pure optical pattern. Horizontal line fills only in band areas — no diagonal, no curves.
A plain, solid-filled letterform in a single colour on clean white. No rings, no stripes, no optical rhythm. Just a static, inert letter. Without the concentric stroke system, there is no identity — it is just typography.
