## Overview

Clean and professional landing page for an AI assistant. Ideal for landing pages, modern websites. AI-ready template. Fluent Design started as Microsoft's answer to flat design fatigue — acrylic blur, depth layers, motion that actually meant something. It was gorgeous but underused. Then Copilot happened.

The AI era forced Fluent to grow up fast. Suddenly you needed interfaces that could surface AI suggestions without overwhelming a spreadsheet jockey in Accounting. The system evolved from decorative depth into functional layering: AI responses float on acrylic surfaces, contextual actions emerge through motion, and the whole thing still feels like Office — just smarter. That's the trick. Enterprise users don't want revolution. They want Tuesday to feel slightly better than Monday.

What makes Fluent's AI chapter interesting is restraint. Microsoft could have gone full sci-fi. Instead they kept the rounded corners, the familiar toolbar rhythms, the quiet material language — and threaded intelligence through it like electricity through existing wiring. The depth system now serves hierarchy of human vs. machine content. Motion signals when AI is thinking. Acrylic separates your work from its suggestions. It's infrastructure design, not decoration.

- No oversaturated accent colors (saturation cap: 80%)
- No 3-column equal-width feature layouts — use zig-zag or asymmetric grid
- No `h-screen` — use `min-h-[100dvh]`
- No AI copywriting clichés: "Elevate", "Seamless", "Unleash", "Next-Gen"
- No broken external image links — use picsum.photos or inline SVG
- No generic lorem ipsum in demos

## Implementation Checklist

- ☐ Foco em produtividade com IA.

## 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.
