+### 📊 Session Management
+
+**GameSession** - Track play sessions with common and game-specific stats.
+
+```swift
+// Create a game-specific stats type
+struct MyGameStats: GameSpecificStats {
+    var specialWins: Int = 0
+    
+    init() {}
+    
+    var displayItems: [StatDisplayItem] {
+        [StatDisplayItem(icon: "star.fill", iconColor: .yellow, 
+                        label: "Special Wins", value: "\(specialWins)")]
+    }
+}
+
+// Create session type alias
+typealias MyGameSession = GameSession<MyGameStats>
+```
+
+**SessionManagedGame Protocol** - Add session management to your game state.
+
+```swift
+@Observable
+class GameState: SessionManagedGame {
+    typealias Stats = MyGameStats
+    
+    var currentSession: MyGameSession?
+    var sessionHistory: [MyGameSession] = []
+    
+    // Record round results
+    func completeRound(winnings: Int, bet: Int) {
+        recordSessionRound(
+            winnings: winnings,
+            betAmount: bet,
+            outcome: winnings > 0 ? .win : .lose
+        ) { stats in
+            if wasSpecialWin {
+                stats.specialWins += 1
+            }
+        }
+    }
+}
+```
+
+**Session UI Components:**
+
+```swift
+// End session button
+EndSessionButton {
+    state.showEndSessionConfirmation = true
+}
+
+// Current session header with live stats
+CurrentSessionHeader(
+    duration: session.duration,
+    roundsPlayed: session.roundsPlayed,
+    netResult: session.netResult,
+    onEndSession: { /* confirm */ }
+)
+
+// Session row for history list
+SessionSummaryRow(
+    styleDisplayName: "Vegas Strip",
+    duration: session.duration,
+    roundsPlayed: session.roundsPlayed,
+    netResult: session.netResult,
+    startTime: session.startTime,
+    isActive: false,
+    endReason: .manualEnd
+)
+```
+
+**SessionFormatter** - Format session data for display.
+
+```swift
+SessionFormatter.formatDuration(3600)     // "01h 00min"
+SessionFormatter.formatMoney(500)         // "$500"
+SessionFormatter.formatMoney(-250)        // "-$250"
+SessionFormatter.formatPercent(65.5)      // "65.5%"
+```

+# CasinoKit Session System
+
+This document describes the generic session tracking system in CasinoKit that can be used by any casino game.
+
+## Overview
+
+The session system provides:
+- **Session tracking**: Track play sessions from start to end
+- **Common statistics**: Wins, losses, pushes, bets, duration
+- **Game-specific statistics**: Each game can track its own custom stats
+- **Session history**: Store and display completed sessions
+- **Aggregated statistics**: Combine stats across all sessions
+

+
+```swift
+public struct GameSession<Stats: GameSpecificStats>: Codable, Identifiable {
+    // Identity
+    let id: UUID
+    let gameStyle: String
+    
+    // Timing
+    let startTime: Date
+    var endTime: Date?
+    
+    // Balance
+    let startingBalance: Int
+    var endingBalance: Int
+    
+    // Common statistics (all games track these)
+    var roundsPlayed: Int
+    var wins: Int
+    var losses: Int
+    var pushes: Int
+    var totalWinnings: Int
+    var biggestWin: Int
+    var biggestLoss: Int
+    var totalBetAmount: Int
+    var biggestBet: Int
+    
+    // Game-specific statistics
+    var gameStats: Stats
+    
+    // Computed
+    var isActive: Bool
+    var duration: TimeInterval
+    var netResult: Int
+    var winRate: Double
+    var averageBet: Int
+}
+```
+
+### GameSpecificStats Protocol
+
+Each game implements this to track game-specific statistics.
+
+```swift
+public protocol GameSpecificStats: Codable, Equatable, Sendable {
+    init()
+    var displayItems: [StatDisplayItem] { get }
+}
+```
+
+**Example: Blackjack Implementation**
+
+```swift
+struct BlackjackStats: GameSpecificStats {
+    var blackjacks: Int = 0
+    var busts: Int = 0
+    var surrenders: Int = 0
+    var doubles: Int = 0
+    var splits: Int = 0
+    var insuranceTaken: Int = 0
+    var insuranceWon: Int = 0
+    
+    var displayItems: [StatDisplayItem] {
+        [
+            StatDisplayItem(icon: "21.circle.fill", iconColor: .yellow, 
+                          label: "Blackjacks", value: "\(blackjacks)"),
+            StatDisplayItem(icon: "flame.fill", iconColor: .orange,
+                          label: "Busts", value: "\(busts)"),
+            // ... more items
+        ]
+    }
+}
+
+typealias BlackjackSession = GameSession<BlackjackStats>
+```
+
+**Example: Baccarat Implementation**
+
+```swift
+struct BaccaratStats: GameSpecificStats {
+    var naturals: Int = 0
+    var bankerWins: Int = 0
+    var playerWins: Int = 0
+    var ties: Int = 0
+    var playerPairs: Int = 0
+    var bankerPairs: Int = 0
+    
+    var displayItems: [StatDisplayItem] {
+        [
+            StatDisplayItem(icon: "sparkles", iconColor: .yellow,
+                          label: "Naturals", value: "\(naturals)"),
+            // ... more items
+        ]
+    }
+}
+
+typealias BaccaratSession = GameSession<BaccaratStats>
+```
+
+### SessionManagedGame Protocol
+
+Game state classes conform to this to get session management.
+
+```swift
+@MainActor
+public protocol SessionManagedGame: AnyObject {
+    associatedtype Stats: GameSpecificStats
+    
+    var currentSession: GameSession<Stats>? { get set }
+    var sessionHistory: [GameSession<Stats>] { get set }
+    var balance: Int { get set }
+    var startingBalance: Int { get }
+    var currentGameStyle: String { get }
+    
+    func saveGameData()
+    func resetForNewSession()
+}
+```
+
+**Default implementations provided:**
+- `ensureActiveSession()` - Create session if needed
+- `startNewSession()` - Start a fresh session
+- `endCurrentSession(reason:)` - End and archive session
+- `endSessionAndStartNew()` - End current and start new
+- `handleSessionGameOver()` - Handle running out of money
+- `recordSessionRound(...)` - Record a round result
+- `aggregatedStats` - Get combined stats
+- `sessions(forStyle:)` - Filter by game style
+
+## Integration Guide
+
+### Step 1: Create Game-Specific Stats
+
+```swift
+// In your game's Models folder
+struct MyGameStats: GameSpecificStats {
+    var customStat1: Int = 0
+    var customStat2: Int = 0
+    
+    init() {}
+    
+    var displayItems: [StatDisplayItem] {
+        [
+            StatDisplayItem(
+                icon: "star.fill",
+                iconColor: .yellow,
+                label: "Custom Stat 1",
+                value: "\(customStat1)"
+            ),
+            // Add more as needed
+        ]
+    }
+}
+
+typealias MyGameSession = GameSession<MyGameStats>
+```
+
+### Step 2: Update Game Data for Persistence
+
+```swift
+struct MyGameData: PersistableGameData, SessionPersistable {
+    var currentSession: MyGameSession?
+    var sessionHistory: [MyGameSession]
+    var balance: Int
+    // ... other data
+}
+```
+
+### Step 3: Conform GameState to SessionManagedGame
+
+```swift
+@Observable
+@MainActor
+final class GameState: SessionManagedGame {
+    typealias Stats = MyGameStats
+    
+    var currentSession: MyGameSession?
+    var sessionHistory: [MyGameSession] = []
+    var balance: Int
+    
+    var startingBalance: Int { settings.startingBalance }
+    var currentGameStyle: String { settings.gameStyle.rawValue }
+    
+    func saveGameData() {
+        // Persist to CloudSyncManager
+    }
+    
+    func resetForNewSession() {
+        // Reset game-specific state (reshuffle deck, clear history, etc.)
+    }
+    
+    init() {
+        // Load saved data...
+        ensureActiveSession()
+    }
+}
+```
+
+### Step 4: Record Rounds
+
+```swift
+// At the end of each round:
+recordSessionRound(
+    winnings: roundWinnings,
+    betAmount: betAmount,
+    outcome: .win // or .lose, .push
+) { stats in
+    // Update game-specific stats
+    if wasSpecialOutcome {
+        stats.customStat1 += 1
+    }
+}
+```
+
+### Step 5: Add Aggregation Extension (Optional)
+
+```swift
+extension Array where Element == MyGameSession {
+    func aggregatedGameStats() -> MyGameStats {
+        var combined = MyGameStats()
+        for session in self {
+            combined.customStat1 += session.gameStats.customStat1
+            combined.customStat2 += session.gameStats.customStat2
+        }
+        return combined
+    }
+}
+```
+
+## UI Components
+
+CasinoKit provides reusable UI components:
+
+### EndSessionButton
+A styled button to trigger ending a session.
+
+```swift
+EndSessionButton {
+    state.showEndSessionConfirmation = true
+}
+```
+
+### EndSessionConfirmation
+A confirmation dialog showing session summary.
+
+```swift
+EndSessionConfirmation(
+    sessionDuration: session.duration,
+    netResult: session.netResult,
+    onConfirm: { state.endSessionAndStartNew() },
+    onCancel: { dismiss() }
+)
+```
+
+### CurrentSessionHeader
+Header showing active session with end button.
+
+```swift
+CurrentSessionHeader(
+    duration: session.duration,
+    roundsPlayed: session.roundsPlayed,
+    netResult: session.netResult,
+    onEndSession: { /* show confirmation */ }
+)
+```
+
+### SessionSummaryRow
+A row for displaying a session in a list.
+
+```swift
+SessionSummaryRow(
+    styleDisplayName: "Vegas Strip",
+    duration: session.duration,
+    roundsPlayed: session.roundsPlayed,
+    netResult: session.netResult,
+    startTime: session.startTime,
+    isActive: session.isActive,
+    endReason: session.endReason
+)
+```
+
+### GameStatRow
+Display a single stat item from `displayItems`.
+
+```swift
+ForEach(session.gameStats.displayItems) { item in
+    GameStatRow(item: item)
+}
+```
+
+## SessionFormatter
+
+Utility for formatting session data:
+
+```swift
+SessionFormatter.formatDuration(seconds)      // "02h 15min"
+SessionFormatter.formatMoney(amount)          // "$500" or "-$250"
+SessionFormatter.formatPercent(value)         // "65.5%"
+SessionFormatter.formatSessionDate(date)      // "Dec 29, 2024, 10:30 AM"
+SessionFormatter.formatRelativeDate(date)     // "2h ago"
+```
+

+
+## Best Practices
+
+1. **Always call `ensureActiveSession()` on init** - Guarantees a session exists.
+
+2. **Update balance in session after each round** - The `recordSessionRound` method handles this.
+
+3. **Implement `resetForNewSession()` properly** - Clear round history, reshuffle decks, reset UI state.
+
+4. **Use type aliases for convenience** - `typealias BlackjackSession = GameSession<BlackjackStats>`
+
+5. **Provide aggregation extensions** - For combining game-specific stats across sessions.
+
+6. **Use `StatDisplayItem` for consistent UI** - Makes stats display automatic in UI components.
+
+## Data Storage
+
+Session data is stored via `CloudSyncManager` which handles:
+- Local persistence to UserDefaults
+- iCloud sync when available
+- Conflict resolution using `lastModified` timestamps
+
+The `SessionPersistable` protocol extends `PersistableGameData` to add:
+```swift
+public protocol SessionPersistable {
+    associatedtype Stats: GameSpecificStats
+    var currentSession: GameSession<Stats>? { get set }
+    var sessionHistory: [GameSession<Stats>] { get set }
+}
+```
