## Overview

Grunge Design visual system, translated from the Claude Artisan catalog for use in digital products. Distressed textures, dirt, splatter, torn edges; Chaotic overlapping type, broken legibility

- **Category:** brutalist
- **Era:** 1990s
- **Origin:** David Carson (Ray Gun magazine); reaction to clean corporate design.
- **Reference:** David Carson, Ray Gun magazine (1990s).
- **Structural base:** shell de aplicação com navegação e cartões

**Defining traits:**
- Distressed textures, dirt, splatter, torn edges
- Chaotic overlapping type, broken legibility
- Photocopied, degraded, layered collage
- Anti-grid experimental layout

## Colors

- **bg** — #1a1815
- **surface** — #24211c
- **surface-strong** — #2e2a23
- **border** — #55503f
- **text** — #ece6d8
- **text-muted** — #a89f8a
- **primary** — #c1391f
- **accent** — #d9b23c
- **ink** — #0c0b09

## Typography

- Display: 'Oswald', 'Impact', 'Arial Narrow', sans-serif
- Body: 'Courier New', 'Special Elite', monospace
- Mono: 'Courier New', ui-monospace, monospace

## Layout

- shell de aplicação com navegação e cartões
- Use a responsive grid and preserve content hierarchy.
- Collapse columns below 768px without horizontal overflow.

## Elevation & Depth

- Distressed textures, dirt, splatter, torn edges; Chaotic overlapping type, broken legibility; Photocopied, degraded, layered collage; Anti-grid experimental layout; sombras e elevação

## Shapes

- Radius scale: 0px, 2px, 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.
