We run [Rocely](https://www.rocely.com/en), a recipe and meal-planning PWA. Users who install it to their home screen come back far more often than users who just bookmark it, so a reliable install step matters for retention. We want one install flow that works the same way regardless of browser, instead of branching our UI based on what the browser supports.
