main.py

"""
main.py — Application entry point and main CustomTkinter window.

WINDOW STRUCTURE:
  Header bar (dark)  — app name + CSV button + version
  CTkTabview         — tab navigation with bright text labels
    📊 Dashboard     — overview, alerts, quick-log
    🐍 Animals       — collection profiles
    📋 Husbandry     — daily care logs
    ❤️  Health        — medical records
    🥚 Clutches      — breeding cycle management
    🐣 Hatchlings    — per-hatchling tracking
    🌳 Pedigree & CoI — ancestor viewer + inbreeding calculator

ERROR LOGGING:
  Errors in refresh_all() are caught and written silently to:
  %LOCALAPPDATA%\BallPythonDB\error.log
  This means UI never freezes on a non-critical refresh error.

DB PATH:
  %LOCALAPPDATA%\BallPythonDB\ballpython.db
  Using AppData avoids PyInstaller's temp folder which is deleted on exit.
