  The site uses Select, Title, Background and BackTop; the Geocaching page
  also uses Button, Card and Divider. These use custom layout,
  colors, sizing and localized labels. The shopping-bag icon is extracted from
  this library for device purchase links.

- The Geocaching worker bundles **@reticulum/core 0.9.0** and
  **@reticulum/lxmf 0.9.0**, by **Henri Bergius and contributors**, under
  [EUPL 1.2](./geocaching/licenses/EUPL-1.2.txt).
  [Upstream source](https://github.com/bergie/reticulum-js) is also included in
  the generated worker's source map. The packages are unmodified; Trail Mate's
  adapter sets resource limits and injects compression on outbound reply links.
- The Geocaching map uses **Leaflet 1.9.4**, by **Vladimir Agafonkin and
  contributors**, under BSD-2-Clause. The map displays OpenStreetMap attribution;
  tiles are loaded only for the current interactive viewport using browser cache
  semantics. No offline tile download or prefetch is provided.
  [Tile usage policy](https://operations.osmfoundation.org/policies/tiles/).
- The Geocaching worker uses **seek-bzip 2.0.0** (C. Scott Ananian, Eli Skeggs,
  Kevin Kwok and contributors, MIT) and **buffer 6.0.3** (Feross Aboukhadijeh and
  contributors, MIT), plus buffer's base64-js/ieee754 dependencies. Their notices
  are copied into the generated `geocaching/dist/THIRD-PARTY.txt` at build time.
