## Overview

Composio-inspired nocturnal landing page. Ideal for integrações de ferramentas, apis, plataformas developer, automação de agentes. AI-ready template. The nocturnal interface didn't emerge from nowhere. It's the logical endpoint of a decade-long drift away from the sterile white dashboards that dominated developer tooling through the 2010s. When terminal culture collided with modern UI expectations, we got dark themes. But dark themes alone are lazy — they're just inverted colors with no soul. The cyan glow aesthetic traces back to sci-fi film UI (think Tron Legacy's light disc sequences, Blade Runner 2049's holographic interfaces) and the real-world glow of CRT phosphors that early hackers stared at until 3am.

Composio's visual language takes that lineage seriously. The cyan-on-dark palette isn't decorative — it's functional hierarchy borrowed from cockpit instrumentation, where luminous accents against deep backgrounds reduce cognitive load during extended sessions. This matters when your users are developers wiring up AI agent integrations at midnight, not browsing a lifestyle brand at lunch.

The futuristic tech aesthetic has matured past the 'slap a gradient on it' phase. What works now is restraint: selective luminosity, deep blacks that actually breathe, and typography that doesn't fight the glow for attention. Composio Cyber Nocturnal represents that maturity — it knows when to pulse and when to recede.

- **Hover states:** Subtle color shift + shadow adjustment over 200ms.
- **Page transitions:** Fade only (200ms).
- **Performance:** Only transform and opacity animated. No layout-triggering properties.


## Shapes

Base corner radius: 0px. See rounded tokens in front matter for the full scale.


## Components

- **Primary Button:** Sharp edges (0px) shape. Accent color fill. Hover: 8% darken + subtle lift shadow. Active: -1px translate tactile press. Font weight 600. No outer glows.
- **Secondary / Ghost Button:** Outline variant. 1.5px border in muted color. Text in primary color. Hover: subtle background fill.
- **Cards:** Sharp edges (0px) corners. Surface background. Subtle shadow (0 2px 12px rgba(0,0,0,0.06)). 1px border stroke.
- **Inputs:** Label above input. 1px border stroke. Focus ring: 2px accent color offset 2px. Error text below in semantic red. No floating labels.
- **Navigation:** Primary surface background. Active item: accent color indicator. Font weight 500 when active.
- **Skeletons:** Shimmer animation matching component dimensions. No circular spinners.
- **Empty States:** Icon-based composition with descriptive text and action button.


## Do's and Don'ts

- No emojis in UI — use icon system only (Lucide, Heroicons)
- No rounded corners — sharp edges only
- No subtle shadows — use hard borders instead
- No pure black (#000000) — use off-black or charcoal variants
- 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

## 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.
