## Overview
Sistema visual Grainy Gradient, traduzido do catálogo Claude Artisan para uso em produtos digitais. Smooth color gradient overlaid with fine grain; Reduces banding, adds tactility
- **Categoria:** Textura, material & renderização
- **Era:** 2021–present
- **Origem:** Adding grain to smooth gradients for depth.
- **Exemplo:** Vercel/Linear backgrounds; A24-style sites.
- **Base estrutural:** composição editorial com grade tipográfica
**Traços definidores:**
- Smooth color gradient overlaid with fine grain
- Reduces banding, adds tactility
- Soft dreamy color fields
- Premium editorial feel
## Colors
- **bg** — #1c1626
- **surface** — #241d31
- **surface-strong** — #2e2540
- **border** — rgba(255,255,255,0.10)
- **text** — #f4f1f8
- **text-muted** — #b8aec7
- **primary** — #ff8a5c
- **accent** — #7c6cf0
- **grad-a** — #2a1b3d
- **grad-b** — #6b3fa0
- **grad-c** — #ff8a5c
## Typography
- Display: 'Söhne', 'Inter', system-ui, sans-serif
- Corpo: 'Inter', system-ui, -apple-system, sans-serif
- Mono: 'JetBrains Mono', ui-monospace, monospace
## Layout
- composição editorial com grade tipográfica
- Use uma grade responsiva e preserve a hierarquia de conteúdo.
- Colapse colunas abaixo de 768px sem overflow horizontal.
## Elevation & Depth
- Smooth color gradient overlaid with fine grain; Reduces banding, adds tactility; Soft dreamy color fields; Premium editorial feel; sombras e elevação
## Shapes
- Raios: 8px, 14px, 22px.
## 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.Relacionados
