A/B recipe comparison view — side-by-side diff of two versions

The version history shows a diff of changes over time for one recipe. I want the ability to open two different recipes side-by-side and compare them — for example, my base carnitas recipe vs a variant I created for a lower-fat version. A side-by-side view with ingredients and method shown in parallel columns, with differences highlighted, would be very useful for deliberate recipe development.
