Repterra Web — full game: base building, power grid, taming & breeding, aquatic raiders, day/night, save/load

- Isometric canvas RTS vs dinosaur waves (fan demake of Repterra)
- Economy: houses/taxes, farms, foresters, quarries; colonist staffing
- Power grid: generators extend build range; brownout + recovery
- Defense: walls/gates, watchtowers (AA), cannon towers (ground-only)
- Taming: Primal Pen + Tamers collar weakened dinos; pets obey commands
- Breeding: tamed pairs incubate eggs at the pen; hatchlings grow up
- 7 dino species incl. flying Pteranodons and lake-raiding Suchomimus
- Telegraphed waves with direction arrows; day-15 final horde; 3 difficulties
- Day/night cycle, fog of war, minimap, synth audio, 1x-3x speeds
- Save/Load/Continue + dawn autosave (full JSON state snapshots)
- Tests: 80-assertion headless suite, browser boot + E2E, balance harness
