Split 60 40 Story

The left 60% (576px) holds one asset slowly pushing 1→1.06 as the lead (for the length of the shot), a 3px white seam, and the right 40% a 30px two-line title plus three pastel chips (24px bold) popping in with the voice at 1.0 / 1.6 / 2.2s (back.out); at 6.8s asset, seam and text all close on the same frame
