Initial commit: Thön, a Vildhjarta-inspired idle game

Idle/incremental game about a small circle of "bärare" weaving open a
breach to Thön from a disused sawmill in Skellefteå, Sweden. Reskins
the Djupet engine (passive resources, map-click visits, escalating
events, win/lose meters) around Vildhjarta's mythology — masks, the
Thörnepherian language, and a discoverable lore codex.

Vanilla TypeScript + Vite + Leaflet, with generated key art, location
art, and character portraits under public/img/.
