   Terminal Noir — refined + animated
   Replace your existing styles.css with this file.
   - Monospace-first terminal aesthetic
   - Subtle animated accents: glows, flicker, entrance, floating
   - Pure-CSS (no JS changes required)
   - Keeps selectors: body.theme-cyber, .wrap, .site-header, .terminal, .btn, .gallery, etc.
