This is the animation reference doc from the axiom-swiftui suite. You'd reach for it when SwiftUI animations aren't behaving or you need the correct pattern instead of just slapping .animation() on everything. The main skill README warns that animation issues compound and explicitly routes animation problems here, which suggests it covers both the API surface and the common gotchas that lead to janky or broken transitions. It's part of a larger diagnostic system with routes for debugging, navigation, layout, and performance, so it probably assumes you've already tried the obvious stuff. No preview of what's actually inside the reference, but given the suite's depth elsewhere, expect more than just modifier signatures.
