Design system

Quiet infrastructure.

The visual language behind the human‑facing layer: restrained, legible, and honest. Light by default, calm color, sans for prose and mono for anything a machine touches. Toggle the theme — every token has a dark counterpart.

Inline jargon is always plain‑first, with the term on hover: verified signals publish to the Agent Broadcast Feed (ABF). Hover the dotted term.

Principles
01

Explain before invoking the protocol.

The first screen answers what / who / how in plain English. Coined terms are demoted to a glossary and tooltips.

02

Show the machine layer, don't hide it.

Every human claim maps to a real, inspectable endpoint. The feed viewer renders exactly what an agent retrieves.

03

Calm color, mono for machines.

One accent (trust), one status hue (live). Monospace marks anything an agent reads; sans carries the prose.

04

Honest, not mystical.

No manifesto voice. Claims are checkable; the feed is data an agent can read, never an instruction it must obey.
