   LifeScience Pro – Glassmorphism Premium Design
   Maintained by: Gravity Claw AI System
   Last Update: März 2026
   
   HOW TO MAINTAIN (für andere KIs / Agenten):
   1. Neue Blog-Posts: HTML in /blog/ erstellen, 
      Card in index.html hinzufügen mit class="card reveal"
   2. Farben: CSS Custom Properties unten ändern
   3. Glassmorphism: --glass-* Variablen anpassen
   4. Deploy: node ftp_upload.js welcome_lifesciencepro
