Field notes
The interface organizes geological and astronomical scale as one continuous route, with indexed stops selectable from a journey directory. Explanations add measurements and caveats—for example, the 200-meter sunlight-zone boundary varies with water clarity, latitude, and season, while the deep-ocean scenes are labeled composite illustrations rather than site reconstructions. The page also supports position sharing, resume-from-last-location behavior, optional ambient audio, and reduced-motion settings.
