How to interpret the specifications

Bundlephobia measurements use its standard package build and may exclude peer dependencies. Unpacked npm distribution size includes shipped files and is a different measurement. Module declarations do not prove tree-shaking or runtime compatibility.

Advisories apply to this package version directly; transitive dependencies need separate inspection. Repository signals describe the whole repository and are current observations, including on historical-version pages.
