  • "Мартышка" → "Обезьяна" (Monkey)
  • "Кустик" → "Древесный дух" (Treeling)
• Improved achievement titles for better Russian flow:
  • "Победа духа над телом" → "Сила духа" (Mind Over Matter)
  • "Воздушный легион" → "Птицы одного полёта" (Birds of a Feather)
  • "Специалист по временам года" → "Мастер сезонов" (Seasonal Specialist)
  • And 10+ more titles
• Standardized capitalization of animal names in lists
• Fixed grammatical errors in item lists

generic.json:

• Made notification messages more natural:
  • "Вы все вспомнили!" → "Вы всё просмотрели!"

tasks.json:

• Fixed critical typo: "сторонни[ интеграция[" → "сторонних интеграциях"
• Improved achievement descriptions to use neutral forms
• Fixed grammatical errors:
