## Overview

Teletext visual system, translated from the Claude Artisan catalog for use in digital products. Extremely low-res blocky mosaic character graphics; Strict 7-color palette (black + red/green/yellow/blue/magenta/cyan/white), no gradients

- **Category:** niche
- **Era:** 1970s–90s
- **Origin:** Broadcast teletext services - BBC Ceefax and ITV Oracle in the UK (1974 onward), French videotex - decoded by dedicated receiver chips through the 1990s.
- **Reference:** BBC Ceefax; ITV Oracle; French Minitel terminal screens; teletext subtitle overlays.
- **Structural base:** hero, superfície, conteúdo e grade responsiva

**Defining traits:**
- Extremely low-res blocky mosaic character graphics
- Strict 7-color palette (black + red/green/yellow/blue/magenta/cyan/white), no gradients
- Monospaced blocky type only, no anti-aliasing
- Page-number navigation motif

## Colors

- **bg** — #000000

## Typography

- Display: 'Bedstead', 'Courier New', monospace
- Body: 'Bedstead', 'Courier New', monospace
- Mono: 'Bedstead', 'Courier New', 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

- Extremely low-res blocky mosaic character graphics; Strict 7-color palette (black + red/green/yellow/blue/magenta/cyan/white), no gradients; Monospaced blocky type only, no anti-aliasing; Page-number navigation motif; sombras e elevação; transparência e blur

## Shapes

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

## 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.
