Vendored files are integrity-checked at build time. Preserve their licenses and attribution when redistributing source, bundles or exports. Runtime and development npm dependencies retain their package-specific licenses; this table describes the separately bundled assets, not an exhaustive npm dependency license inventory.

内置资源与联网获取内容均需保留各自署名及许可。构建会生成 `lib/THIRD_PARTY_NOTICES.txt` 与 `lib/LEAFLET_NOTICES.txt`，HTML 导出也保留相应声明。
