+**Homeworld update, 9 September 2026:** all 13 cards and 26 physical faces are verified, including native population/battle values and occupied income symbols. The internal gallery supplies both faces, complete original gameplay prose, enlarged inspection and thirteen original bundled illustrations. Separate typed custody and population helpers are tested; actual Homeworld gameplay, occupation and effect integration remain unfinished and gated. See [HOMEWORLD_IMPLEMENTATION.md](HOMEWORLD_IMPLEMENTATION.md) and [HOMEWORLD_COMPONENT_AUDIT.md](HOMEWORLD_COMPONENT_AUDIT.md). Earlier missing-Homeworld statements below are historical.
