## Overview

Dark SaaS landing page hero section. Ideal for b2b saas, ai tools, plataformas de desenvolvedores, landing pages tech, startups, apis e sdks. AI-ready template. The dark SaaS hero didn't emerge from nowhere — it's the logical endpoint of a decade-long shift away from the friendly, white-space-heavy interfaces that dominated early SaaS. When Stripe went dark in 2018, it signaled that developer tools could look like luxury goods. The rest of the industry followed. Dark backgrounds became shorthand for technical sophistication.

Liquid glass is the latest evolution of this lineage. It borrows from Apple's visionOS material language and the frosted-glass experiments that Figma and Linear popularized, but pushes further — introducing refraction, caustics, and fluid distortion that make UI elements feel physically present. The video background underneath isn't decorative; it's structural. It provides the light source that makes the glass effect legible.

What makes this pattern distinct from generic glassmorphism is intentionality. The glass isn't slapped on a gradient. It reacts to content beneath it, creating depth hierarchy without relying on drop shadows or borders. It's a post-flat, post-neumorphic approach that finally treats the screen as a volumetric space rather than a stack of cards.

## 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.
