/* ==========================================================================
   style.css — Global styles for Conor Ashlee-Purle portfolio

   Architecture:
   - Multi-page site: index.html, project.html, about.html, commission.html,
     extra.html, familyArchive.html
   - All interactive elements use .interactive class (opacity 0.85 → 1 on hover)
   - Gallery images have their own opacity rules (0.85 → 1, no scale)
   - Background: blackGlitch.webp + noise overlay (injected by noise.js)

   Z-index layers:
     10     .centered-container (main menu)
     50     .section-screen (family archive)
    100     .top-left-actions (home/about buttons)
    100     .preloader
   1000     .lightbox
   1001     .lightbox-nav, .lightbox-close
  10000     #device-check-overlay (mobile gate — topmost)
