Heritage: UNESCO Croatia property list and intangible heritage list. Cultural properties, natural properties, national parks and intangible traditions are distinct categories. The reading distinguishes Plitvice's World Heritage designation from Croatia's eight national parks, and includes Pag, Lepoglava and Hvar in its lacemaking context.

City and sight pins: curated approximate settlement or landmark coordinates cross-referenced to the named Wikipedia articles. City pins represent settlement centres, not administrative boundaries. Landscape pins represent a named place, not a guaranteed entrance, trailhead or walking route. Coast and inland groups are informal educational groupings, not counties. The map does not claim to teach county boundaries or a complete river network.

Country outline: selected HR feature from the repository's public/countries.geojson, Natural Earth generalised country geography, public domain. Small islands and coastal detail may be omitted. All city and sight coordinates were checked against the outline with a 3 km margin for generalisation.

Photographs: ten distinct topic photos plus an existing Split banner. Geography (Zlatni Rat), history (Split Peristyle), nature (Plitvice) and landmarks (Dubrovnik) reuse local Croatian lesson assets. Language (Baška tablet), culture (Klapa Sagena in concert), economy (Rijeka port), politics (Banski dvori), food (štrukli) and people (central Zagreb) have new local copies, each with a .source.json file preserving the original page, photographer and Creative Commons licence. Every topic retains a visible Commons credit. Both sets were visually checked as contact sheets. Photos illustrate their named subjects, not current opening or restoration conditions.

Quiz review: all 80 existing Croatian seed questions were reviewed. 29 corrections apply at read time through src/lib/croatia-facts-patches.json. Original prompts remain lookup keys; lesson/question IDs and learning progress are preserved. Corrections address inhabited island counts, duplicate dialect choices, an undated tourism percentage, the Krk and Pelješac bridges, euro chronology, national parks versus UNESCO status, turtle habitat versus an unsupported nesting claim, wine regions, national identity and unsupported rankings or population estimates. Source seed literals and database records are unchanged.
