## 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
- **surface** — #000000
- **surface-2** — #1a1a1a
- **text** — #ffffff
- **text-muted** — #00ff00
- **primary** — #00ff00
- **red** — #ff0000
- **yellow** — #ffff00
- **blue** — #0000ff
- **magenta** — #ff00ff
- **cyan** — #00ffff
- **white** — #ffffff

## 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.

## Implementation Checklist

- Contraste WCAG AA; foco visível; navegação por teclado; estados hover/pressed; responsividade; prefers-reduced-motion; Tailwind v4 via @theme.

## Execution Rules

1. Strictly follow the defined visual style.
2. Use high-quality inline SVG icons (Heroicons or Lucide style) — NEVER use emojis as icons.
3. Add `cursor-pointer` and smooth `hover` states (transition-all) on all interactive elements.
4. Required Page Structure:
   - Navbar (Logo + Links + CTA)
   - Hero Section (Impactful Headline + Subtitle + 2 buttons + 3D/Abstract visual element via CSS)
   - Features (3 cards with icons)
   - Testimonials (3 cards)
   - Pricing (3 tiers, highlight the middle one)
   - Final CTA
   - Full Footer with social links, privacy policy, terms of use, contact and SEO links.
5. All text content must be in English.
6. The visual must be CLEARLY distinct — do not create a "default Bootstrap" design. Force the use of the provided design system variables.
7. Use `<style>` tags in the head for custom classes (especially for complex backdrop-filter effects and animations) that Tailwind CDN doesn't cover.
8. Full Responsiveness: Layout must adapt perfectly to Mobile, Tablet and Desktop (vertical stack on mobile).
9. Include basic SEO, Viewport and Open Graph meta tags in `<head>`.
10. Footer must contain: Copyright 2026, Secondary navigation links and Social media icons.
11. Make the creative decisions needed to deliver the complete, functional result now.
