History: AI-driven alternate-history simulator

Pax Historia-style sim where the LLM is the world engine.

- React 19 + Vite 6 + Tailwind v4 + shadcn/ui frontend
- Express single-port backend (/api + /sse + built client + SPA fallback)
- SQLite (better-sqlite3) persistence, one row per game
- MapLibre choropleth map (OpenFreeMap dark + ISO_A3 regions)
- Defensive turn loop: strip fences, balanced-{} extract, parse, clamp 0-100,
  retry-once nudge, generic 'unclear' fallback; never crashes on bad output
- 5 seed presets (wwii-1939, coldwar-1955, modern-2025, no-wwii-1940, aegis-2400)
- LLM client over native fetch w/ injectable transport (mesh-bot pattern);
  LLM_STUB=1 deterministic transport for tests/e2e
- Unit (vitest, 19) + deterministic Playwright e2e
- Multi-stage node:22-slim Docker + Traefik (history.dev.kkhost.pl:4321)
