+Tests live in `tests/`, outside `src/`. `tests/property.test.ts` checks the

 Pure helpers used by a class (for example `matchesStart`, `stepSpring`, or
 `composeNodeStyle`) are module-level `export const`s that the class calls, so
 they can be tested directly without widening the class's interface.
