+/**
+ * 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
