  • Added consistent “가입하기” button behavior that navigates to login/signup.
• Refactor
  • Streamlined screen initialization to load member content only when applicable, improving responsiveness.
  • Consolidated visitor-mode UI into dedicated containers for cleaner, more consistent layouts.
• Style
  • Replaced hard-coded texts with localized string resources for visitor-mode messages and button labels.
