Managing Startup Time as a Budget: How I Deferred SDK Init Across Six Apps
Instead of optimizing startup ad hoc, I switched to allocating a per-phase time budget and defending it. Here's how I deferred SDK init across six Rork-built apps and added a CI gate that fails the build when the budget is exceeded.
