 Sigrea core provides reactive primitives, deep signals, and scope-based
 molecule lifecycles. It is built on
 [alien-signals](https://github.com/stackblitz/alien-signals).
 
-- **Core primitives.** `signal`, `computed`, `toSignal`, `deepSignal`, `watch`, and `watchEffect`.
+- **Core primitives.** `signal`, `computed`, `toSignal`, `deepSignal`,
+  `watch`, and `watchEffect`.
 - **Lifecycles.** `Scope`, `onMount`, and `onUnmount` for cleanup boundaries.
 - **Molecules.** `molecule()` is a lifecycle container that doesn't render UI.
 - **Composition.** Build molecule trees via `get()`.
-- **Testing.** `trackMolecule` + `disposeTrackedMolecules` helps clean up molecule instances in tests.

 ## Adapters
 
 Official adapters connect Sigrea molecules and signals to UI frameworks:
