Public design system
A calm shell that lets AI output take the stage
The brand gradient is reserved for generate moments only — everywhere else the interface stays neutral so streaming output is the thing your eye lands on. Three-zone layout, prompt composer behavior, streaming and stop states, and semantic status are all specified — the parts most AI-chat starters leave undefined until launch.

- Indigo — Primary actions, brand
