- Enhanced Scoreboard rankings with significantly larger, consistent font sizes (text-2xl) for better readability
- Rebranded "TEAM_IDENTIFIER" to "PLAYER" and "TOTAL_POINTS" to "POINTS" across the platform (Scoreboard, Matrix, User Menu)
- Updated navigation: Renamed "SCOREBOARD" to "SCORES" in the nav bar and dynamic page titles
- Modernized User Dropdown menu with a dedicated "PLAYER" header and "LOGOUT" action
- Improved Score Matrix and Score Graph titles for consistency with the new "Player" terminology
- Added CAPTCHA human verification (svg-captcha) to Login and Registration flows for enhanced security
- Optimized frontend assets by migrating Tailwind and JetBrains Mono to local hosting
- Refactored Admin panel: Renamed "Operators" to "Users" and improved layout alignment
