+ * 1. Jest does not support custom coverage reporters (facebook/jest#9112), so
+ *    we rely on the default `CoverageReporter` running before us and use the
+ *   `coverageMap` that it places on the aggregated result state.
+ *
+ * 2. `istanbul-reports` does not support writing to a custom stream, so we need
+ *    to temporarily override `process.stdout.write` 😱.
+ *
+ * {@link https://github.com/facebook/jest/blob/v27.3.1/packages/jest-reporters/src/CoverageReporter.ts#L103}
