How it behaves
Exactly what the prompt builds — every timing and easing is specified, so the result matches the demo.
- Two rows of 268×80px tiles (#141414) with every logo forced to white.
- Row 1 scrolls left, row 2 scrolls right, both at a steady 40s per loop, linear.
- Each row renders its logos 3× and moves exactly one third of its width, so the loop is seamless at any screen size.
- Hovering a row pauses it. prefers-reduced-motion: reduce turns the motion off.
- Screen readers hear the list once (the duplicate copies are aria-hidden).
