Arday (2015) ↔ Zwozdiak-Myers, redacted "ZM" (2009) — structure map
Each page is a heavily downsampled thumbnail — enough to see paragraph shape and length, not enough to read the text. Colored bars mark passages the alignment scan matched between the two documents: solid blocks are exact-run matches, thin markers are fuzzy (paraphrase-level) matches. Scroll near a highlighted bar and its counterpart lights up on the other side, with the actual quoted text shown below. Click a bar to jump both panels to it.
