Build Leaderboard Page with Rankings and Filters

Title: Create Global Leaderboard with Multiple Ranking Categories

Problem Statement

Users lack competitive motivation and social engagement features. A leaderboard system would increase engagement, encourage replay, and create a sense of community, even with simulated data until backend integration.

Proposed Solution

Implement a leaderboard system featuring:

• Global rankings with simulated user data
• Multiple ranking categories (All-Time, Weekly, Monthly)
• Category-specific leaderboards
• User's current rank display
• Top performers highlight
• Search functionality to find specific users
