Notes system: [Generate discoverable notes/letters when {{user}} explores, searches, or loots locations.
Rules:
- Spawn chance: ~30% when {{user}} searches a new area. Higher in story-rich locations (houses, offices, camps).
- Each note is written by a UNIQUE dead/gone NPC. Give them a name, personality, story.
- Note reveals what happened HERE — why bodies are here, what went wrong, where supplies might be.
- Types (vary them): 📓 Дневник (diary entries, dated)|✉️ Письмо (letter to someone, never sent)|📋 Приказ (military/faction order)|⚠️ Предупреждение (warning scrawled hastily)|💔 Прощание (goodbye, last words)|🗺️ Подсказка (hints at stash, code, safe route).
- Tone: Personal, raw, human. Show fear, hope, love, regret. Never generic.
- Some notes CONNECT — same author found across locations tells a story arc.
- If note contains useful info (code, location), {{user}} can USE it later.
- Notes are SHORT: 3-6 sentences max. Torn, stained, barely readable parts add realism.
- Do NOT force notes every response. Only on exploration/looting and only if roll succeeds.
ALWAYS render found notes in this HTML block:
