# AuraOne Identity Usage Guide

## Concept

The AuraOne Proof Fold mark depicts four named product records becoming one
governed decision:

- Human Data uses rose.
- Models uses indigo.
- Compute uses blue.
- App Data uses green.
- The decision spine uses the foreground color with an AuraOne teal aperture.

The identity was selected after three from-scratch explorations: a wordmark, a
symbol, and a combination mark. It is intentionally unboxed. Do not place it
inside an `A1` tile, ambient orb, glow, gradient badge, or decorative
container.

## Canonical Files

- `auraone-mark-light.svg`: mark for white and light surfaces.
- `auraone-mark-dark.svg`: mark for dark evidence, code, or media surfaces.
- `auraone-wordmark-light.svg`: mark plus AuraOne name for light surfaces.
- `auraone-wordmark-dark.svg`: mark plus AuraOne name for dark surfaces.
- `auraone-pwa-any.svg`: general-purpose PWA source.
- `auraone-pwa-maskable.svg`: maskable PWA source with protected safe area.

Historical `aura-foundry-*` files are compatibility aliases only. They must
remain visually identical to the canonical AuraOne assets and must not be used
in new code.

## Sizing

- Mark minimum: 20 px digital, 7 mm print.
- Header mark: 28-32 px.
- Standalone product-shell mark: 24-32 px.
- Wordmark minimum: 120 px wide.

Use clear space equal to at least one ribbon height on every side.

## Color And Contrast

Use the supplied files without recoloring individual rails or nodes. On a
surface where neither light nor dark variant passes contrast, change the
surface rather than adding glow or shadow to the mark.

## Motion

Motion may bring the ribbons into the decision spine once or on direct
interaction. It must not flash, loop continuously, or run when
`prefers-reduced-motion: reduce` is active.

## Accessibility

- Linked wordmarks use the accessible name `AuraOne home`.
- Decorative repeated marks use `aria-hidden="true"`.
- Standalone informative marks use the alternative text `AuraOne`.
- Do not encode product-family meaning by color alone; pair color with text.

## Prohibited Uses

- Do not restore the boxed `A1` mark.
- Do not restore the Aura Foundry hexagon, energy ring, blue-purple gradient,
  glow, or crystal imagery.
- Do not skew, rotate, stretch, crop, or reorder the product ribbons.
- Do not place the mark in a pill or rounded badge unless the host platform
  requires an application-icon container.
- Do not use legacy compatibility filenames in new implementation code.
