Pins show representative places, not administrative boundaries, entrances or trails. Two learning regions (coast and interior) are informal educational groupings, not official subdivisions. Only a cities map is included; municipal and river games are not claimed. Country outline: selected ME feature from the repository's public/countries.geojson, Natural Earth generalised country geography, public domain. https://www.naturalearthdata.com/about/terms-of-use/ Photographs: reuse the repository's ten local Montenegro topic photographs from src/lib/european-facts-heroes.json. The guide retains individual Commons source links, author names and licence labels. The hero reuses the Ostrog photograph; it is not represented as a separate image. The photographs were visually reviewed as a contact sheet. Quiz review: 80 existing seed questions reviewed. Read-time corrections retain original prompt lookup keys, question IDs and progress. Corrected issues include the incorrect highest-peak claim, ambiguous lake rankings, wrong film-director attribution, invented port exclusivity, overbroad historical claims and undated population. No seed or database records were changed.
