## Do's and Don'ts

- Do: follow the tokens and the structural composition.
- Do: maintain WCAG AA contrast and `prefers-reduced-motion`.

## Design System Variables

```css
--bg: #ffffff, --fg: #1f1f1f, --accent: #1473e6, --surface: #f8f8f8, --radius: 8px, --spacing: 16px, --font-display: 'Adobe Clean', 'Source Sans Pro', system-ui, sans-serif, --font-body: 'Adobe Clean', 'Source Sans Pro', system-ui, sans-serif
```

## 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.
