   Transgalaxy — styles.css
   Organized in sections so the site can grow predictably:
     1. Design tokens (change the brand here)
     2. Base / reset
     3. Layout primitives (.container, .section)
     4. Components (buttons, brand, cards, ...)
     5. Page sections (hero, platform, audiences, intelligence, ...)
     6. Responsive
   When adding new UI, prefer reusing tokens + existing primitives.
