BRAND GUIDE

ETHRAEON visual and verbal identity, governed under the brand constitution (T5-RIGID)

Purpose. ETHRAEON presents as a constitutional runtime and evidence control layer: governance-native AI infrastructure. The brand register is institutional and formal-technical. Light parchment is the default marketing register; the void surface is used only for the constitutional-runtime dark UI. This guide is the reference for the color system, typography, voice and tone, and claims policy.

ETHRAEON Forest

#194534

Default page ground (parchment-50, light register).

Typography

Display - Cinzel

ETHRAEON CONSTITUTIONAL RUNTIME

Editorial serif - Cormorant Garamond

Governance survives substrate replacement. The ledger persists.

Body and UI - Archivo

Runtime enforcement via the PEP and PDP pattern, with an immutable evidence chain and hash verification.

Evidence and hashes - IBM Plex Mono

sha256:verified | 16 filed | 73 specifications | 9 families

Heading weight 700, body weight 400, base size 16px, line-height 1.6. Header letter-spacing 0.15em.

Voice and Tone

Institutional register, formal-technical, third-person declarative.
State facts. Never speculate.
Measurements are as-measured. Claims are as-documented.
Governance language over marketing language.
Precision over enthusiasm. No superlatives unless quantified.
No future-tense promises on public surfaces.
Public surfaces avoid promotional or hype terminology, revenue or valuation-inflation phrasing, vague trust language, and internal prototype code-names.
