I wouldn't say they're mutually exclusive, the narrative can still form part of the scrapbook although it is easy for the focus to shift. Like
@Warthog I've found myself starting a scrapbook TL only for it to become almost entirely prose because I've started feeling more confident in and enjoying writing the latter. Granted you do sometimes need the occasional return to the scrapbook style for big offscreen events because "Hey Ben, how about that [SPORTS TEAM]? Also did you hear the news the Jiangxi Soviet has collapsed?" is hard to write naturally.
