Why it works
The story is short but mechanically precise: it names the exact change made (moving a description box above the fold), explains why it should work (eye flow, price-transparency nudge), and ties it to a concrete revenue number. That specificity is rare for a micro-case-study this brief. The coin-flip between Breakthrough and Efficiency does not arise here because the headline leads unambiguously with a number going up.
