/**
 * View Data Layer Tests - Leaderboards Functionality
 *
 * This test file will cover the view data layer for leaderboards functionality.
 *
 * The view data layer is responsible for:
 * - DTO → UI model mapping
 * - Formatting, sorting, and grouping
 * - Derived fields and defaults
 * - UI-specific semantics
 *
 * This layer isolates the UI from API churn by providing a stable interface
 * between the API layer and the presentation layer.
 *
 * Test coverage will include:
 * - Leaderboard data transformation and ranking calculations
 * - Driver leaderboard view models (overall, per-race, per-season)
 * - Team leaderboard view models (constructor standings, team performance)
 * - Leaderboard statistics and metrics formatting
 * - Derived leaderboard fields (points, positions, gaps, intervals, etc.)
 * - Default values and fallbacks for leaderboard views
 * - Leaderboard-specific formatting (lap times, gaps, points, positions, etc.)
 * - Data grouping and categorization for leaderboard components
 * - Leaderboard sorting and filtering view models
 * - Real-time leaderboard updates and state management
 * - Historical leaderboard data transformation
 * - Leaderboard comparison and trend analysis view models
