Logo & Mark
- Set the wordmark in Satoshi, 600 weight, Anvil in signal green.
- Pair only with the strata mark.
- Use on void or reversed on bone, with clear space around it.
- Letter the internal 'brain' or 'forge' names into public marks.
- Recolor, gradient, or shadow the strata.
- Mix Anvil with operation-specific imagery; the spine stays generic.
Color
- Default to void and bone. Green marks live jobs and runtime state.
- Keep the palette identical to Kinetic API; they are one family.
- Use gold only for seals or internal marks.
- Flood backgrounds with green.
- Open new hues. The palette is closed.
- Drift the green; it must match the Kinetic signal exactly.
Typography
Voice & Tone
Canonical, not ad hoc.
Anvil is the single source of state. We describe one runtime, one contract.
Generic, not leaky.
The public contract uses generic nouns only. Operation specifics never surface.
Precise, not verbose.
Name the resource, the job, the scope. The spec is the source of truth.
Foundational, not flashy.
The spine holds everything up quietly. It does not compete for attention.
- Lead with resources, jobs, and the stateful contract.
- Keep the public vocabulary generic.
- Point reference apps and brains at the spine, never the reverse.
- Surface internal 'brain', 'forge', or operation nouns in public copy.
- Promise behavior the conformance suite does not cover.
- Use startup or hype language.
Elements
Settling layers
Stacked bars that settle onto a base: state accruing. The Anvil signature motif.
The ledger
Jobs and events set in Geist Mono. The record reads as an append-only ledger.
Hairline squares
Single-weight frames hold resources and rows. Structure shown, never decorated.
Live state
A green node marks a live job or runtime state. Used sparingly, never as fill.
Strict measure
Content holds a 1140px measure. Generous void around dense reference blocks.
Hold the contract
If it does not serve the canonical contract, cut it. The spine earns trust by being exact.
