## Overview

Cyanotype visual system, translated from the Claude Artisan catalog for use in digital products. Prussian-blue monochrome photographic prints; White silhouettes on deep blue

- **Category:** texture
- **Era:** 1842–present
- **Origin:** Sir John Herschel's photographic process.
- **Reference:** Anna Atkins botanical cyanotypes.
- **Structural base:** composição editorial com grade tipográfica

**Defining traits:**
- Prussian-blue monochrome photographic prints
- White silhouettes on deep blue
- Botanical/photogram subjects
- Antique handmade quality

## Colors

- **bg** — #0d2c61
- **surface** — #123a7a
- **surface-strong** — #17458f
- **border** — #6f92d1
- **text** — #eaf1ff
- **text-muted** — #b6c9ec
- **primary** — #ffffff
- **accent** — #a9c4f5
- **bleed** — rgba(255, 255, 255, 0.10)

## Typography

- Display: 'Cormorant Garamond', 'Playfair Display', serif
- Body: 'Cormorant Garamond', 'EB Garamond', Georgia, serif
- Mono: 'Courier Prime', ui-monospace, monospace

## Layout

- composição editorial com grade tipográfica
- Use a responsive grid and preserve content hierarchy.
- Collapse columns below 768px without horizontal overflow.

## Elevation & Depth

- Prussian-blue monochrome photographic prints; White silhouettes on deep blue; Botanical/photogram subjects; Antique handmade quality; sombras e elevação

## Shapes

- Radius scale: 2px, 4px, 6px.

## 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.
