Brand system v0.1

Capsules carry work.

The identity reduces the protocol to one durable idea: a portable vessel that holds content, state, ledger, and action without locking the actor to a vendor.

Identity Principles

Protocol first

Lead with the artifact, spec, and proof surfaces. Avoid SaaS conversion patterns.

Portable by form

The capsule silhouette is the master metaphor: bounded, transferable, readable, resumable.

Verification visible

Use meridians, ledger lines, ticks, and version labels to show provenance without security theater.

Quiet technical trust

Dark editorial surfaces, precise copy, and muted accents make the system feel inspectable.

Machine-readable posture

Brand expressions should translate to markdown, SVG, terminal, browser UI, and protocol docs.

Honest status

Prototype, v0.6, dates, checks, and raw links are part of the brand language.

Core mark

A vessel with a ledger.

The mark keeps the existing wireframe capsule but sharpens its meaning: outer shell for transport, meridian for continuity, cross-lines for state layers, and the central protected lane for provenance.

Shell State lines Meridian Ledger core

Logo variants

One mark, several surfaces.

Primary

Default lockup for site headers, docs covers, and repository readmes.

Mark

Small icon, favicon candidate, and canvas fallback for motion scenes.

Seal

Protocol pages, signed examples, conformance status, and trust surfaces.

Stack

Explains content, state, ledger, and action as transportable layers.

Runtime

For Skill, MCP, raw prompt, and any host that can open a capsule.

Sheet

A single reference image for quick review across dark and light contexts.

Visual tokens

Restrained system, durable accents.
