## Overview

Sistema visual ANSI / BBS Art, traduzido do catálogo Claude Artisan para uso em produtos digitais. 16-color ANSI/CP437 block-character art (half-blocks, shading glyphs); Saturated primary/neon palette on black, no gradients

- **Categoria:** Subculturas & estéticas de nicho
- **Era:** 1980s–90s
- **Origem:** Dial-up bulletin board systems used ANSI escape codes and CP437 extended-ASCII to render splash screens and menus, drawn in TheDraw and traded by groups like ACiD and iCE through the 1980s-90s.
- **Exemplo:** Classic BBS login/menu splash screens; ACiD/iCE Productions ANSI art packs; TheDraw-authored door-game menus.
- **Base estrutural:** hero, superfície, conteúdo e grade responsiva

**Traços definidores:**
- 16-color ANSI/CP437 block-character art (half-blocks, shading glyphs)
- Saturated primary/neon palette on black, no gradients
- Blocky extended-ASCII border and shading characters (double-line boxes)
- Monospaced type only, never anti-aliased

## Colors

- **bg** — #000000
- **surface** — #0a0a0a
- **surface-2** — #1c1c1c
- **text** — #c0c0c0
- **text-muted** — #808080
- **primary** — #ff5555
- **accent** — #55ffff
- **yellow** — #ffff55
- **green** — #55ff55
- **magenta** — #ff55ff
- **blue** — #5555ff
- **white** — #ffffff
- **red-dark** — #aa0000

## Typography

- Display: 'Perfect DOS VGA 437', 'Courier New', monospace
- Corpo: 'Perfect DOS VGA 437', 'Courier New', monospace
- Mono: 'Perfect DOS VGA 437', 'Courier New', monospace

## Layout

- hero, superfície, conteúdo e grade responsiva
- Use uma grade responsiva e preserve a hierarquia de conteúdo.
- Colapse colunas abaixo de 768px sem overflow horizontal.

## Elevation & Depth

- 16-color ANSI/CP437 block-character art (half-blocks, shading glyphs); Saturated primary/neon palette on black, no gradients; Blocky extended-ASCII border and shading characters (double-line boxes); Monospaced type only, never anti-aliased; sombras e elevação; transparência e blur

## Shapes

- Raios: 0px, 0px, 0px.

## Components

- Botões mantêm foco visível e estados hover/pressed previsíveis.
- Cartões usam a superfície e a escala de raios definidas nos tokens.
- Formulários exibem labels persistentes, erro textual e foco por teclado.

## Do's and Don'ts

- Faça: respeite os tokens e a composição estrutural indicada.
- Faça: mantenha contraste WCAG AA e `prefers-reduced-motion`.
- Evite: usar o estilo como decoração sem hierarquia funcional.

## Checklist de Implementação

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

## Regras de Execução

1. Siga fielmente o estilo visual determinado.
2. Use ícones SVG inline de alta qualidade (estilo Heroicons ou Lucide) — PROIBIDO usar emojis como ícones.
3. Adicione `cursor-pointer` e estados de `hover` suaves (transition-all) em todos os elementos interativos.
4. Estrutura Obrigatória da Página:
   - Navbar (Logo + Links + CTA)
   - Hero Section (Headline impactante + Subtitle + 2 botões + Elemento visual 3D/Abstrato via CSS)
   - Features (3 cards com ícones)
   - Testimonials (3 cards)
   - Pricing (3 tiers, destaque no central)
   - CTA Final
   - Footer completo com redes sociais, política de privacidade, termos de uso, contato e links SEO.
5. Todo o conteúdo textual deve ser em Português Brasileiro (PT-BR).
6. O visual deve ser CLARAMENTE distinto — não crie um design "padrão Bootstrap". Force o uso das variáveis de design system fornecidas.
7. Use tags `<style>` no head para classes personalizadas (especialmente para os efeitos complexos de backdrop-filter e animações) que o Tailwind via CDN não cobrir.
8. Responsividade Total: O layout deve se adaptar perfeitamente a Mobile, Tablet e Desktop (Stack vertical no mobile).
9. Inclua meta tags básicas de SEO, Viewport e Open Graph no `<head>`.
10. Footer deve conter: Copyright 2026, Links de navegação secundária e Ícones de redes sociais.
11. Assuma as decisões criativas necessárias para entregar o resultado completo e funcional agora.
