Initial commit — Djupet
Idle cult management game set in Malmö, Sweden. Manage Troende, Andakt, Dread, Hemlighet and Kaos while completing the Grand Ritual before investigators shut you down. Lovecraftian flavour, Henderson- tier chaos events, OSM/Leaflet map with dread spread markers across Rosengård, Värnhemstorget, Turning Torso and Øresundsbron. Vanilla TypeScript + Vite, no framework. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
