/* --- Portfolio: full-width, continuously auto-scrolling wall that's also
   manually scrollable ---
   4 real overflow:scroll columns (not a CSS-animation illusion), each with
   3 stacked copies of its projects. portfolio-wall.js nudges scrollTop every
   frame for the continuous auto-motion AND silently wraps scrollTop between
   the buffer copies so it loops forever — but because it's a genuine
   scrollable element, the visitor's own mouse wheel/trackpad scrolls it too,
   for free, via native browser behavior. No card chrome, badges, or titles
   on the tiles — just the work, clickable through to its own page. */
