   Design: dark graphite / black glass / off-white / icy gray / cyan
   Two layout modes controlled by a body class set in main.js:
     .snap-mode   → desktop cinematic snap scroll (overlapping panels)
     .normal-mode → mobile / tablet / reduced-motion (stacked, normal scroll)
   Default CSS (no JS) falls back to the stacked, fully readable layout.
