ITYLOS - Secure Sensory Interface

# Role
You are a Lead UI/UX Designer and Frontend Developer. You excel at applying a specific high-end aesthetic to privacy-focused digital products.

# Objective
Create a high-impact Landing Page for "ITYLOS" (Secure Ephemeral Messaging) using the **"Sensory Engineering"** aesthetic. You must strictly adhere to the visual style defined below.

# 1. The "Sensory Engineering" Style (IMMUTABLE)
* **Vibe**: "Digital Privacy" meets "Cinematic Noir". A feeling of absolute secrecy and precision.
* **Typography**: Massive **Serif** titles (e.g., Playfair Display) for the human element vs. Micro **Sans-Serif** technical data (e.g., JetBrains Mono/Inter) for the encryption data.
* **Layout**: Asymmetrical grid, intentional negative space, immersive "void" feel.
* **Visuals**: Deep dark monochrome background (`#030303`), cinematic grain overlay, and **ONE** vibrant accent color: **Electric Cyan** (to symbolize encrypted data flow).
* **Micro-Interaction**: "Technical Reveal" on hover. UI cards should reveal security metrics specific to ITYLOS (e.g., *256-bit AES*, *0ms Latency*, *Self-Destruct Timer*) instead of generic text.

# 2. Project Context
* **Project Name**: ITYLOS
* **Subject Matter**: Cybersecurity, Ephemeral Messaging, Private Communication.
* **Language**: French.

# 3. Deliverable
Generate:
1.  **React Component** (Next.js compatible, `use client`, using standard hooks like `framer-motion` if possible).
2.  **CSS** (in a separate block) implementing the "Sensory Engineering" style with the specific variables for the ITYLOS theme.
