[ DESIGN SYSTEM ]
One mark, one ontology
Every Nika verb, builtin, feature and run-state has a canonical glyph, color role and motion — declared once in the icon ontology, projected everywhere. Machine-readable: icons.json · icons.ttl · integrator reference.
The marks

A verb is a distinct native execution model. Hue = alive.

- exec
- invoke
- agent

Motion · the dot-matrix register
A pattern is an execution model: infer samples, exec scans, invoke round-trips, the agent orbits its bounded loop — and the butterfly beats its wings.

- Exec · scanline
- Invoke · roundtrip
