## Overview

Atlassian Design System visual system, translated from the Claude Artisan catalog for use in digital products. Friendly-professional productivity tone; Blue/neutral palette, clear hierarchy

- **Category:** flat-platform
- **Era:** 2017–present
- **Origin:** Atlassian.
- **Reference:** Jira; Confluence; Trello.
- **Structural base:** hero, superfície, conteúdo e grade responsiva

**Defining traits:**
- Friendly-professional productivity tone
- Blue/neutral palette, clear hierarchy
- Strong content + accessibility guidance
- Componentized (Atlaskit)

## Colors

- **bg** — #f7f8f9
- **surface** — #ffffff
- **surface-strong** — #f1f2f4
- **border** — #dcdfe4
- **text** — #172b4d
- **text-muted** — #44546f
- **primary** — #0052cc
- **accent** — #36b37e

## Typography

- Display: 'Charlie Sans', 'Segoe UI', system-ui, sans-serif
- Body: 'Charlie Sans', 'Segoe UI', system-ui, -apple-system, sans-serif
- Mono: 'SFMono-Regular', ui-monospace, monospace

## Layout

- hero, superfície, conteúdo e grade responsiva
- Use a responsive grid and preserve content hierarchy.
- Collapse columns below 768px without horizontal overflow.

## Elevation & Depth

- Friendly-professional productivity tone; Blue/neutral palette, clear hierarchy; Strong content + accessibility guidance; Componentized (Atlaskit); sombras e elevação

## Shapes

- Radius scale: 3px, 6px, 10px.

## 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.

## Design System Variables

```css
--bg: #f7f8f9, --fg: #172b4d, --accent: #0052cc, --surface: #ffffff, --radius: 6px, --spacing: 16px, --font-display: 'Charlie Sans', 'Segoe UI', system-ui, sans-serif, --font-body: 'Charlie Sans', 'Segoe UI', system-ui, -apple-system, 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.
