## Overview

Dark-mode-native developer landing page inspired by Supabase. Ideal for plataformas developer, ferramentas open-source, bancos de dados, apis. AI-ready template. Supabase arrived in 2020 positioning itself as the open-source Firebase alternative, but its visual identity told a different story entirely. The emerald green on near-black palette wasn't just a color choice — it was a declaration. While every other developer tool was shipping safe blues and purples, Supabase went full terminal-green-meets-luxury. The effect was immediate: you looked at their dashboard and felt like you were piloting something powerful.

That emerald became synonymous with a new wave of developer tool aesthetics. It proved you could be technical and visually striking simultaneously. The green wasn't friendly or approachable in the conventional SaaS sense — it was confident, almost cinematic. Think sci-fi command centers, not startup landing pages.

The ripple effect across the ecosystem was undeniable. Post-Supabase, we saw a surge of developer tools embracing darker palettes with single saturated accent colors. The playbook they wrote — dark canvas, one bold hue, generous spacing, monospace touches — became the template for an entire generation of dev-focused products that wanted to signal sophistication without sacrificing developer credibility.

## 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.
