Hop.Earth public source
The demo is based on the public DVLPLONDON/Hop repository at commit d712b2bb35340777f8e0fa77e770a25b2c245e8b. The repository is distributed under the MIT License with copyright attributed to Hop.Earth / DVLP Ltd. A copy of that notice is included in this project's LICENSE file.
Adapted technical ideas include Web Mercator coordinate conversion, road-tile parsing, and the local driving-client approach. Hopearth.online adds a new static-host architecture, route definitions, checkpoint progression, timing, scoring, local records, touch controls, pause and fullscreen states, sharing, accessibility labels, and automated test hooks.

The bundled files are the Monaco sample road tiles published in the upstream repository under backend/public/sample-tiles. The demo renders those local samples and does not query Google Maps. Google Maps wording appears only when explaining common search language or describing a third-party product that uses it.
