How it moves
A section that reads as two columns: chapters of prose on one side, one picture frame on the other that stays with the reader as they scroll. As each chapter reaches the reading line the frame takes that chapter's picture: the frame changes shape to the new picture's own crop from its top corner, overshooting a little before it settles, and the picture wipes in along the direction of travel and drifts to rest a beat after the shape lands. The chapters not being read can fade back so the one being read is the one that is lit. Scroll back up and it runs the other way. Without JavaScript, or for a reader who has asked for reduced motion, it is a two-column magazine spread with every chapter's picture beside its own words.
What you can set before you copy
Every one of these is an attribute of the block, so it is the same control the editor's inspector offers after you have pasted. The Motion drawer on a pattern's own page writes your values into the markup before you copy it.
