react-to-print@^2.15.1 declares peerDependencies only up to React/ReactDOM 18, but this package’s peerDependencies allow React/ReactDOM 19. This creates an install-time peer mismatch for React 19 consumers. Consider either keeping react-to-print on a React 19-compatible major, or tightening this package’s React peer range (or moving react-to-print to a peer/optionalPeer with a compatible range).

The coverage script no longer uploads lcov output to Coveralls, but the repo still contains Coveralls configuration (e.g., .coveralls.yml) and a Coveralls badge in the README. If Coveralls reporting is still intended, the upload step should remain; otherwise, please also remove/update the leftover Coveralls config/docs to avoid a broken badge and confusing tooling.
