Карта, маршрут и источники загружаются раздельно, чтобы временная ошибка одного слоя не скрывала остальную страницу.
The map, route and sources load separately so one temporary layer failure does not hide the rest of the page.
Published data and a traveller's private plan remain separate.
Stable public IDs and slugs are identical in every language. Changing language changes the published wording, not the underlying object.
The data date and release revision are exposed through machine contracts and service status.
If a source fails, the last-known state is labelled or the gap is shown; no new fact is inferred.
Exact schedules and prices are not shown without a verified source.
