## Overview

Serious and informative editorial landing page for an investigative journalism platform. Ideal for landing pages, modern websites. AI-ready template. Investigative journalism has always demanded a visual language that says: trust this. The tradition runs deep — from the broadsheet gravity of the early New York Times to the stark, almost clinical layouts ProPublica pioneered in the digital era. These publications understood something fundamental: when you're asking readers to spend forty minutes with a corruption exposé, the design cannot compete with the content. It must recede. It must signal rigor.

The Guardian's 2018 redesign crystallized this thinking for the web age. Egyptian Slab headlines. Generous whitespace. A type hierarchy so clear you could navigate a 6,000-word investigation without ever feeling lost. The Intercept pushed further — monospaced accents, document-style callouts, layouts that evoked declassified files. Every choice whispered authenticity.

What connects these approaches isn't minimalism for its own sake. It's restraint as editorial position. The sobriety of the page becomes an argument: we did the work, we have the evidence, we don't need to shout. Typography carries the weight that sensationalism refuses to.

## 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.
