Fact 351
Riley Tanaka added a hard rule to the experiment notes on March 28, 2023: while pricing is under test, no other layout or UI changes may ship on that page because concurrent changes confound conversion attribution; content and copy changes remain allowed.

put one hard rule in the experiment notes: if pricing is under test, no other layout/UI changes on that page, full stop -- attribution got muddy because of the Mar 2 signup-form change sitting in the same window as EXP-2023-02-pricing-page / `pricing_page_2023q2_rev`. if somebody asks later why some cleanup can't ship during a pricing run, that's the reason. content ok, copy ok, but don't move boxes around while we're trying to read conversion.
