CSS animation-timeline: scroll() is Chromium-only, so the backdrop didn't move for non-Chromium browsers. Replace it with a tiny rAF-throttled scroll handler in site.js (the existing same-origin script — CSP stays strict, no inline JS) that drives a --bg-shift CSS var off scroll position. The board now pans vertically in lock-step with scroll and sits still at rest, in all browsers.
