## Overview

Tidalpunk visual system, translated from the Claude Artisan catalog for use in digital products. Ocean tech: wave/tidal energy, kelp, coral; Blues, teals, salvaged materials

- **Category:** retrofuturism
- **Era:** 2019–present
- **Origin:** Ocean-focused optimistic offshoot of solarpunk.
- **Reference:** Tidalpunk art community.
- **Structural base:** superfície material com conteúdo em camadas

**Defining traits:**
- Ocean tech: wave/tidal energy, kelp, coral
- Blues, teals, salvaged materials
- Sustainable seafaring future
- Hopeful, aquatic, resourceful

## Colors

- **bg** — #0a3d3f
- **surface** — #0f4d4f
- **surface-strong** — #145e60
- **border** — #2f8b83
- **text** — #e8f6f3
- **text-muted** — #a9d6cf
- **primary** — #22b8a3
- **accent** — #d9a441
- **kelp** — #3f7d4a

## Typography

- Display: 'Space Grotesk', 'Poppins', sans-serif
- Body: 'Space Grotesk', 'Inter', system-ui, sans-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

- Ocean tech: wave/tidal energy, kelp, coral; Blues, teals, salvaged materials; Sustainable seafaring future; Hopeful, aquatic, resourceful; sombras e elevação

## Shapes

- Radius scale: 8px, 14px, 22px.

## 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: #0a3d3f, --fg: #e8f6f3, --accent: #22b8a3, --surface: #0f4d4f, --radius: 14px, --spacing: 16px, --font-display: 'Space Grotesk', 'Poppins', sans-serif, --font-body: 'Space Grotesk', 'Inter', 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.
