## Overview

Fluent Design 2 (Fluent 2) visual system, translated from the Claude Artisan catalog for use in digital products. Five fundamentals: light, depth, motion, material, scale; Materials: solid, Mica, Acrylic, Smoke

- **Category:** flat-platform
- **Era:** 2017–present
- **Origin:** Microsoft; Fluent (2017), Fluent 2 refresh (2021+ for Windows 11).
- **Reference:** Windows 11; Microsoft 365; Teams.
- **Structural base:** grade modular responsiva

**Defining traits:**
- Five fundamentals: light, depth, motion, material, scale
- Materials: solid, Mica, Acrylic, Smoke
- Mica tints long-lived surfaces with desktop color
- Reveal highlight, subtle depth, rounded corners

## Colors

- **bg** — #f3f3f3
- **surface** — rgba(255,255,255,0.70)
- **mica** — rgba(243,243,243,0.85)
- **acrylic** — rgba(252,252,252,0.60)
- **text** — #1b1b1b
- **text-muted** — #616161
- **primary** — #0f6cbd
- **accent** — #005fb8
- **stroke** — rgba(0,0,0,0.10)

## Typography

- Display: 'Segoe UI Variable Display', 'Segoe UI', sans-serif
- Body: 'Segoe UI Variable', 'Segoe UI', system-ui, sans-serif
- Mono: 'Cascadia Code', ui-monospace, monospace

## Layout

- grade modular responsiva
- Use a responsive grid and preserve content hierarchy.
- Collapse columns below 768px without horizontal overflow.

## Elevation & Depth

- Five fundamentals: light, depth, motion, material, scale; Materials: solid, Mica, Acrylic, Smoke; Mica tints long-lived surfaces with desktop color; Reveal highlight, subtle depth, rounded corners; sombras e elevação; transparência e blur

## Shapes

- Radius scale: 4px, 8px, 12px.

## 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.
