Implementation notes

• Slide-outs will be integrated in a separate PR.
• The version checks are not ideal, as mentioned in other platforms. Let’s think about how to fix this once i2 is released.

Testing instructions

• Make sure the variant v2 - slide outs is selected in the jetpackConversionRateOptimization A/B test
• Visit the plans page in both Calypso and cloud, expand the plans cards (the first 3 cards), and compare them to the mockups (or screenshots below)
• Switch back to the previous variant and check that the page looks like production
