  • See trace() for usage and addToken for an example

For performance guidelines and tooling, see the Performance Guide.

Pre-merge reviewer checklist

• I've manually tested the PR (e.g. pull and build branch, run the app, test code being changed).
• I confirm that this PR addresses all acceptance criteria described in the ticket it closes and includes the necessary testing evidence such as recordings and or screenshots.

Note

Medium Risk
Adds a global Babel transform that rewrites all import() calls, which can affect runtime module loading semantics if any code relies on native dynamic-import behavior. UI import cleanups are low risk, but the build-step change impacts the entire bundle.

Overview
Prevents Hermes builds from failing on parser-fatal dynamic import() by adding an inlined Babel visitor that rewrites import(x) to Promise.resolve().then(() => require(x)).

Cleans up UI code to import Spinner directly from @metamask/design-system-react-native (and updates the affected Perps toast test mocks accordingly), removing usage of the separate @metamask/design-system-react-native/spinner entrypoint.
