## Overview

Android Holo visual system, translated from the Claude Artisan catalog for use in digital products. Near-black backgrounds, minimal flat chrome; Single glowing cyan/holo-blue accent for all interactive highlights

- **Category:** flat-platform
- **Era:** 2011–2014
- **Origin:** Google's Android 3.0 Honeycomb (2011); carried through Ice Cream Sandwich and Jelly Bean until Material Design replaced it in 2014.
- **Reference:** Android 3.0-4.4 stock UI; Google Now on Jelly Bean; Holo Light/Dark system themes.
- **Structural base:** hero, superfície, conteúdo e grade responsiva

**Defining traits:**
- Near-black backgrounds, minimal flat chrome
- Single glowing cyan/holo-blue accent for all interactive highlights
- Thin geometric condensed sans type, often uppercase labels
- Glow (not shadow) substitutes for elevation

## Colors

- **bg** — #000000
- **surface** — #0c0f10
- **surface-2** — #171b1c
- **text** — #e8f7fa
- **text-muted** — #8a9a9d

## Typography

- Display: 'Roboto Condensed', 'Droid Sans', sans-serif
- Body: 'Roboto Condensed', 'Droid Sans', 'Helvetica Neue', Arial, sans-serif
- Mono: 'Droid Sans Mono', ui-monospace, monospace

## Layout

- hero, superfície, conteúdo e grade responsiva
- Use a responsive grid and preserve content hierarchy.
- Collapse columns below 768px without horizontal overflow.

## Elevation & Depth

- Near-black backgrounds, minimal flat chrome; Single glowing cyan/holo-blue accent for all interactive highlights; Thin geometric condensed sans type, often uppercase labels; Glow (not shadow) substitutes for elevation; sombras e elevação; transparência e blur

## Shapes

- Radius scale: 0px, 2px, 2px.

## Components

- Buttons keep visible focus and predictable hover/pressed states.
- Cards use the surface and radius scale from the tokens.
- Forms expose persistent labels, textual errors, and keyboard focus.

## Do's and Don'ts

- Do: follow the tokens and the structural composition.
- Do: maintain WCAG AA contrast and `prefers-reduced-motion`.
- Avoid: using the style as decoration without functional hierarchy.
