## Overview

Material Design 3 / Material You visual system, translated from the Claude Artisan catalog for use in digital products. Dynamic color extracted from user wallpaper (tonal palettes); Larger rounded shapes, shape-morphing tokens

- **Category:** flat-platform
- **Era:** 2021–present
- **Origin:** Google; Material You (2021), Material 3 Expressive (Google I/O 2025).
- **Reference:** Android 12+; Google apps; Wear OS 5.
- **Structural base:** shell de aplicação com navegação e cartões

**Defining traits:**
- Dynamic color extracted from user wallpaper (tonal palettes)
- Larger rounded shapes, shape-morphing tokens
- Expressive spring-physics motion
- Design tokens as single source of truth; updated components

## Colors

- **bg** — #fef7ff
- **surface** — #fef7ff
- **surface-container** — #f3edf7
- **surface-variant** — #e7e0ec
- **text** — #1d1b20
- **text-muted** — #49454f
- **primary** — #6750a4
- **on-primary** — #ffffff
- **secondary** — #625b71
- **tertiary** — #7d5260
- **outline** — #79747e
- **error** — #b3261e

## Typography

- Display: 'Roboto Flex', 'Roboto', system-ui, sans-serif
- Body: 'Roboto', 'Roboto Flex', system-ui, sans-serif
- Mono: 'Roboto Mono', 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

- Dynamic color extracted from user wallpaper (tonal palettes); Larger rounded shapes, shape-morphing tokens; Expressive spring-physics motion; Design tokens as single source of truth; updated components; sombras e elevação; transparência e blur

## Shapes

- Radius scale: 8px, 12px, 16px.

## 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.
