## Overview

Sumi-e (Japanese Ink Wash) visual system, translated from the Claude Artisan catalog for use in digital products. Monochrome black ink gradients (bokashi) on cream rice-paper backgrounds; Visible brush-stroke texture and ink-bleed edges

- **Category:** historical
- **Era:** 14th century–present
- **Origin:** Traditional East Asian ink wash painting, brought to Japan via Zen Buddhist monks from Song-dynasty China.
- **Reference:** Sesshu Toyo's landscape scrolls; Hasegawa Tohaku 'Pine Trees' screen.
- **Structural base:** superfície material com conteúdo em camadas

**Defining traits:**
- Monochrome black ink gradients (bokashi) on cream rice-paper backgrounds
- Visible brush-stroke texture and ink-bleed edges
- Deliberate negative space (ma) as a compositional element
- Asymmetric, organic compositions with a single red seal (hanko) accent

## Colors

- **bg** — #f4efe4
- **surface** — #faf6ec
- **surface-2** — #ede5d3
- **text** — #1c1c1c
- **text-muted** — #5a564c
- **primary** — #232323
- **accent** — #b13d2c
- **ink-grey** — #8c8676
- **ink-wash** — #3d3a33

## Typography

- Display: 'Zen Old Mincho', 'Shippori Mincho', serif
- Body: 'Shippori Mincho', 'Noto Serif JP', 'Zen Old Mincho', serif
- Mono: ui-monospace, monospace

## Layout

- superfície material com conteúdo em camadas
- Use a responsive grid and preserve content hierarchy.
- Collapse columns below 768px without horizontal overflow.

## Elevation & Depth

- Monochrome black ink gradients (bokashi) on cream rice-paper backgrounds; Visible brush-stroke texture and ink-bleed edges; Deliberate negative space (ma) as a compositional element; Asymmetric, organic compositions with a single red seal (hanko) accent; sombras e elevação; transparência e blur

## Shapes

- Radius scale: 2px, 6px, 14px.

## 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

## 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.
