A trusted-by wall of drawn marks gliding leftward between two hairlines on a mathematically exact loop, soft-masked at both frame edges

This is the format it was composed for. Switch above to see it lay itself out for another — same animation, re-arranged for the frame.

A 'trusted by' logo marquee that loops seamlessly. Eight abstract company marks drawn from circles, triangles, rounded rects and arcs, each with the company name in mono beside it, sliding leftward at a constant speed between two hairlines. Duplicate the row so the seam never shows and make the loop exact — the last frame has to land back on the first frame's offset. Keep the marks muted, fade the strip out into the frame edges with a soft gradient, and put a quiet mono label above it.
