+# Database Migration for Streaks Table
+
+This document describes the database schema changes needed for the streak tracking feature.
+
+## Streaks Table Schema
+
+The following SQL should be executed to create the `streaks` table in the database:
+
+```sql
+CREATE TABLE IF NOT EXISTS streaks (
+  user_id UUID PRIMARY KEY REFERENCES users(id) ON DELETE CASCADE,
+  current_streak_length INTEGER NOT NULL DEFAULT 0,
+  longest_streak_length INTEGER NOT NULL DEFAULT 0,
+  current_streak_last_date DATE NOT NULL
+);
+
+CREATE INDEX idx_streaks_user_id ON streaks(user_id);
+```
+
+## Table Description
+
+- `user_id`: Foreign key reference to the users table. Primary key for this table.
+- `current_streak_length`: The user's current consecutive days streak.
+- `longest_streak_length`: The longest streak the user has ever achieved.
+- `current_streak_last_date`: The date of the user's last completed puzzle.
+
+## Notes
+
+- The streak is updated when a user completes a daily puzzle.
+- If a user completes a puzzle the day after their last completion, the streak increments by 1.
+- If a user misses a day, the current streak resets to 1 (or 0 if they fail).
+- The longest streak is preserved across streak resets.

+# Implementation Summary: Daily Score & Streak Tracking
+
+This document summarizes the implementation of daily score and streak tracking features for the Zimi puzzle game.
+
+## Changes Made
+
+### 1. Database Functions (`app/lib/db/db.js`)
+- **`getStreak()`**: Retrieves the current user's streak information
+- **`updateStreak(completed)`**: Updates user's streak based on puzzle completion
+  - Increments streak if completed yesterday's puzzle
+  - Resets streak to 1 if missed days (or 0 if failed)
+  - Maintains longest streak record
+  - Prevents duplicate updates on the same day
+
+### 2. API Route (`app/api/submit-score/route.js`)
+- **POST `/api/submit-score`**: Endpoint for submitting scores
+  - Accepts `{ milliseconds: number | null }` in request body
+  - Calls `submitDailyScore()` to record the score
+  - Calls `updateStreak()` to update the user's streak
+  - Returns streak data on success
+  - Returns 401 if user not authenticated
+
+### 3. UI Components
+
+#### `app/ui/streak-popup.js`
+- Non-intrusive popup showing user's current streak after completion
+- Animated with motion library
+- Displays streak length and encouragement message
+
+#### `app/ui/login-prompt-modal.js`
+- Modal shown to non-authenticated users who complete puzzles
+- Encourages users to sign in to track progress
+- Explains benefits of tracking streaks
+
+### 4. Game Session Integration (`app/ui/game-session.js`)
+- Imports `useSession` from NextAuth to check authentication status
+- Submits score automatically when game is finished
+- Shows appropriate modal based on authentication status:
+  - Authenticated + completed: Shows streak popup
+  - Unauthenticated + completed: Shows login prompt
+  - Failed (3 strikes): Still submits (resets streak to 0)
+
+### 5. Layout Update (`app/layout.js`)
+- Re-enabled `<UserMenu />` component in header
+- Users can now sign in/out from the UI
+
+### 6. TypeScript Declarations (`types/app.d.ts`)
+- Added type definitions for new database functions
+
+### 7. Documentation (`STREAKS_MIGRATION.md`)
+- SQL schema for `streaks` table
+- Field descriptions
+- Notes on streak logic
+
+## Database Schema
+
+The `streaks` table must be created in the database:
+
+```sql
+CREATE TABLE IF NOT EXISTS streaks (
+  user_id UUID PRIMARY KEY REFERENCES users(id) ON DELETE CASCADE,
+  current_streak_length INTEGER NOT NULL DEFAULT 0,
+  longest_streak_length INTEGER NOT NULL DEFAULT 0,
+  current_streak_last_date DATE NOT NULL
+);
+```
+
+## User Flow
+
+### For Authenticated Users:
+1. User completes daily puzzle
+2. Score automatically submitted to backend
+3. Streak calculated and updated
+4. Streak popup appears showing current streak
+5. User can dismiss popup and continue
+
+### For Non-Authenticated Users:
+1. User completes daily puzzle
+2. Login prompt modal appears
+3. User can sign in to start tracking or dismiss
+4. If dismissed, can still share results
+
+## Key Features
+
+✅ Automatic score submission on game completion
+✅ Streak tracking with proper date handling
+✅ Non-intrusive UI notifications
+✅ Encourages user engagement through login prompts
+✅ Handles edge cases (duplicate submissions, date boundaries, failed games)
+✅ No security vulnerabilities detected
+✅ Maintains existing game functionality
+
+## Testing Notes
+
+- All existing unit tests pass
+- Code review completed and feedback addressed
+- Security scan completed with no issues found
+- Manual testing recommended for:
+  - Completing puzzles while authenticated
+  - Completing puzzles while not authenticated
+  - Multi-day streak building
+  - Streak reset on missed days
+  - Failed game handling
+
+## Dependencies
+
+No new dependencies added. Uses existing packages:
+- next-auth (authentication)
+- postgres (database)
+- @mui/material (UI components)
+- motion (animations)

+# User Experience Guide: Streak Tracking Feature
+
+This document describes how users will experience the new streak tracking feature.
+
+## For New/Anonymous Users
+
+### Before Signing In
+1. User plays and completes the daily puzzle
+2. A modal appears titled "Track Your Progress! 📊"
+3. The modal explains the benefits:
+   - 🔥 Start your streak
+   - 🏆 Compete on the leaderboard
+   - 📈 Track your progress over time
+4. User can either:
+   - Click "Sign In to Start Tracking" → Redirects to Google OAuth
+   - Click "Maybe Later" → Closes modal, can continue playing
+
+### User Menu (Header)
+- User icon in the top-right corner of the page
+- Click to open menu with "Sign in" option
+- Available at all times, not just after game completion
+
+## For Authenticated Users
+
+### After Signing In
+1. User's name appears next to the user icon in the header
+2. User menu now shows "Sign Out" option instead of "Sign in"
+
+### First Daily Puzzle Completion
+1. User completes the puzzle (matches all tiles correctly)
+2. Score is automatically submitted to the backend
+3. A streak popup appears with:
+   - 🔥 Fire emoji (animated scale-in)
+   - "Streak Started!" message
+   - "1 Day" in purple text
+   - "Keep it up! Come back tomorrow to maintain your streak."
+4. User clicks anywhere to dismiss the popup
+5. Can then share results as before
+
+### Subsequent Daily Completions
+
+#### Consecutive Days (Yesterday was completed)
+1. User completes today's puzzle
+2. Streak popup shows:
+   - "Streak Updated!" message
+   - Current streak count (e.g., "3 Days")
+   - Encouragement message
+
+#### After Missing a Day
+1. User completes a puzzle after missing one or more days
+2. Streak resets to 1
+3. Longest streak is preserved in the database
+4. Popup shows "Streak Started!" with "1 Day"
+
+#### Failed Puzzle (3 Strikes)
+1. User gets 3 strikes and fails the puzzle
+2. Current streak resets to 0
+3. No popup is shown (game failed)
+4. Score is recorded as null in the database
+
+### Streak Persistence
+- Streaks are tracked per user in the database
+- Current streak length is shown after each completion
+- Longest streak ever achieved is preserved
+- Last completion date is tracked to determine continuity
+
+## UI Components
+
+### Streak Popup
+- **Style**: Clean dialog with purple border, centered content
+- **Animation**: Scale-in effect for engagement
+- **Dismissal**: Click anywhere outside or on the popup
+- **Timing**: Appears 500ms after score submission completes
+
+### Login Prompt Modal
+- **Style**: Full-width dialog with purple border
+- **Features**: 
+  - Clear benefit explanations
+  - Highlighted feature list in purple box
+  - Two clear action buttons
+- **Timing**: Appears 1000ms after puzzle completion (for anonymous users)
+
+### User Menu
+- **Location**: Top-right corner of header
+- **Always visible**: Available on all pages
+- **States**:
+  - Not signed in: Shows user icon, menu has "Sign in" option
+  - Signed in: Shows user name + icon, menu has "Sign Out" option
+
+## Technical Details
+
+### Score Submission
+- Automatically triggered when game is finished
+- One submission per day (duplicates prevented)
+- Includes completion time for successful attempts
+- Includes null for failed attempts (3 strikes)
+
+### Streak Calculation
+- Checked against yesterday's date
+- Yesterday's completion → Increment streak
+- Same day completion → No change (duplicate)
+- Older than yesterday → Reset to 1
+- Failed game → Reset to 0
+
+### Privacy & Security
+- Only authenticated users can track streaks
+- Scores tied to user account via session
+- No sensitive data exposed in frontend
+- API validates authentication on every request
+
+## Error Handling
+
+### Network Errors
+- Failed submissions log errors to console
+- User can still share results
+- Score can be manually submitted later if needed
+
+### Database Errors
+- Handled gracefully with error responses
+- User sees normal game completion flow
+- Errors logged on backend for monitoring
+
+## Future Enhancements (Not in this PR)
+
+Potential additions that could build on this feature:
+- Display longest streak in user profile
+- Streak recovery (grace period for missed days)
+- Streak milestones and achievements
+- Social sharing of streak achievements
+- Streak leaderboard alongside time leaderboard

+# Quick Reference: Streak Tracking Feature
+
+## 🚀 Quick Start
+
+### For Developers
+
+1. **Database Setup** (Required before deployment)
+   ```sql
+   CREATE TABLE IF NOT EXISTS streaks (
+     user_id UUID PRIMARY KEY REFERENCES users(id) ON DELETE CASCADE,
+     current_streak_length INTEGER NOT NULL DEFAULT 0,
+     longest_streak_length INTEGER NOT NULL DEFAULT 0,
+     current_streak_last_date DATE NOT NULL
+   );
+   CREATE INDEX idx_streaks_user_id ON streaks(user_id);
+   ```
+
+2. **Environment Variables** (Ensure these exist)
+   - `DATABASE_URL` or `POSTGRES_URL` - PostgreSQL connection string
+   - `GOOGLE_CLIENT_ID` - Google OAuth client ID
+   - `GOOGLE_CLIENT_SECRET` - Google OAuth client secret
+   - `NEXTAUTH_URL` - Application URL
+   - `NEXTAUTH_SECRET` - NextAuth secret key
+
+3. **Testing Locally**
+   ```bash
+   npm install
+   npm run dev
+   ```
+   Visit `http://localhost:3000` and try completing a puzzle
+
+## 📋 Feature Overview
+
+### What Was Built
+
+| Component | Purpose | File |
+|-----------|---------|------|
+| Database Functions | Track and update user streaks | `app/lib/db/db.js` |
+| API Endpoint | Submit scores and update streaks | `app/api/submit-score/route.js` |
+| Streak Popup | Show streak after completion | `app/ui/streak-popup.js` |
+| Login Prompt | Encourage login for tracking | `app/ui/login-prompt-modal.js` |
+| Game Integration | Auto-submit scores | `app/ui/game-session.js` |
+| User Menu | Login/logout interface | `app/layout.js` |
+
+### How It Works
+
+```
+User completes puzzle
+    ↓
+Is user authenticated?
+    ↓                ↓
+   YES              NO
+    ↓                ↓
+Submit score    Show login prompt
+    ↓
+Update streak
+    ↓
+Show streak popup
+```
+
+## 🧪 Testing Scenarios
+
+### Manual Test Cases
+
+1. **Anonymous User Completes Puzzle**
+   - Expected: Login prompt modal appears
+   - Expected: Can dismiss and continue
+   - Expected: Can click "Sign In" to authenticate
+
+2. **New User First Completion**
+   - Expected: Streak popup shows "Streak Started! 1 Day"
+   - Expected: Popup is dismissable
+   - Expected: Score appears on leaderboard
+
+3. **User Completes on Consecutive Days**
+   - Day 1: Complete puzzle → "1 Day"
+   - Day 2: Complete puzzle → "2 Days"
+   - Day 3: Complete puzzle → "3 Days"
+   - Expected: Streak increments each day
+
+4. **User Misses a Day**
+   - Day 1: Complete puzzle → "1 Day"
+   - Day 2: Skip
+   - Day 3: Complete puzzle → "1 Day" (reset)
+   - Expected: Streak resets but longest is preserved
+
+5. **User Fails Puzzle (3 Strikes)**
+   - Complete with 3 strikes
+   - Expected: No popup shown
+   - Expected: Streak resets to 0
+   - Expected: Score shows as failed in leaderboard
+
+6. **Duplicate Completion Same Day**
+   - Complete puzzle once
+   - Try to complete again (refresh page, etc.)
+   - Expected: Streak doesn't change
+   - Expected: No duplicate submissions
+
+## 🐛 Common Issues
+
+### Streak Not Updating
+- Check database has streaks table
+- Verify user is authenticated
+- Check console for API errors
+- Ensure DATABASE_URL is set correctly
+
+### Login Not Working
+- Verify Google OAuth credentials
+- Check NEXTAUTH_URL matches your domain
+- Ensure NEXTAUTH_SECRET is set
+- Check NextAuth configuration
+
+### Popup Not Appearing
+- Check browser console for errors
+- Verify motion library is installed
+- Check if game completion is detected
+- Test with different browsers

+
+## 💡 Tips for Customization
+
+### Change Popup Timing
+```javascript
+// In app/ui/game-session.js
+setTimeout(() => setShowStreakPopup(true), 500); // Change 500 to desired ms
+setTimeout(() => setShowLoginPrompt(true), 1000); // Change 1000 to desired ms
+```
+
+### Modify Streak Colors
+```javascript
+// In app/ui/streak-popup.js
+color: '#9333ea' // Change to any color
+border: '3px solid #9333ea' // Change border color
+```
+
+### Adjust Streak Logic
+```javascript
+// In app/lib/db/db.js, line 96
+// Current: Resets streak to 1 if not consecutive
+// To make it more forgiving, you could add grace periods
+```
+
+## 📊 Database Schema
+
+```sql
+-- Main tables involved
+users (id, name, email, password)
+daily_scores (user_id, date, milliseconds)
+streaks (user_id, current_streak_length, longest_streak_length, current_streak_last_date)
+```
+
+## 🔐 Security
+
+- ✅ Authentication required for score submission
+- ✅ Server-side validation of user sessions
+- ✅ SQL injection prevention via parameterized queries
+- ✅ No sensitive data exposed in frontend
+- ✅ 0 vulnerabilities found in security scan
+
+## 🚢 Deployment Checklist
+
+- [ ] Create streaks table in production database
+- [ ] Verify environment variables are set
+- [ ] Test authentication flow works
+- [ ] Verify score submission works
+- [ ] Test streak calculation with real dates
+- [ ] Monitor error logs for issues
+- [ ] Test on mobile devices
+- [ ] Verify popup animations work smoothly

+# on it, or send the connection details to a hosting platform environment.
+# The branch DATABASE_URL is available to you via:
+# "${{ steps.create_neon_branch.outputs.db_url_with_pooler }}".
+# It's important you don't log the DATABASE_URL as output as it contains a username and
+# password for your database.
+# For example, you can uncomment the lines below to run a database migration command:
+#      - name: Run Migrations
+#        run: npm run db:migrate
+#        env:
+#          # to use pooled connection

+#          # OR to use unpooled connection
+#          # DATABASE_URL: "${{ steps.create_neon_branch.outputs.db_url }}"
+
+# Following the step above, which runs database migrations, you may want to check
+# for schema changes in your database. We recommend using the following action to
+# post a comment to your pull request with the schema diff. For this action to work,
+# you also need to give permissions to the workflow job to be able to post comments
+# and read your repository contents. Add the following permissions to the workflow job:
+#
+# permissions:
+#   contents: read
+#   pull-requests: write
+#
+# You can also check out https://github.com/neondatabase/schema-diff-action for more
+# information on how to use the schema diff action.

-# Implementation Summary: Daily Score & Streak Tracking
-
-This document summarizes the implementation of daily score and streak tracking features for the Zimi puzzle game.
-
-## Changes Made
-
-### 1. Database Functions (`app/lib/db/db.js`)
-- **`getStreak()`**: Retrieves the current user's streak information
-- **`updateStreak(completed)`**: Updates user's streak based on puzzle completion
-  - Increments streak if completed yesterday's puzzle
-  - Resets streak to 1 if missed days (or 0 if failed)
-  - Maintains longest streak record
-  - Prevents duplicate updates on the same day
-
-### 2. API Route (`app/api/submit-score/route.js`)
-- **POST `/api/submit-score`**: Endpoint for submitting scores
-  - Accepts `{ milliseconds: number | null }` in request body
-  - Calls `submitDailyScore()` to record the score
-  - Calls `updateStreak()` to update the user's streak
-  - Returns streak data on success
-  - Returns 401 if user not authenticated
-
-### 3. UI Components
-
-#### `app/ui/streak-popup.js`
-- Non-intrusive popup showing user's current streak after completion
-- Animated with motion library
-- Displays streak length and encouragement message
-
-#### `app/ui/login-prompt-modal.js`
-- Modal shown to non-authenticated users who complete puzzles
-- Encourages users to sign in to track progress
-- Explains benefits of tracking streaks
-
-### 4. Game Session Integration (`app/ui/game-session.js`)
-- Imports `useSession` from NextAuth to check authentication status
-- Submits score automatically when game is finished
-- Shows appropriate modal based on authentication status:
-  - Authenticated + completed: Shows streak popup
-  - Unauthenticated + completed: Shows login prompt
-  - Failed (3 strikes): Still submits (resets streak to 0)
-
-### 5. Layout Update (`app/layout.js`)
-- Re-enabled `<UserMenu />` component in header
-- Users can now sign in/out from the UI
-
-### 6. TypeScript Declarations (`types/app.d.ts`)
-- Added type definitions for new database functions
-
-### 7. Documentation (`STREAKS_MIGRATION.md`)
-- SQL schema for `streaks` table
-- Field descriptions
-- Notes on streak logic
-
-## Database Schema
-
-The `streaks` table must be created in the database:
-
-```sql
-CREATE TABLE IF NOT EXISTS streaks (
-  user_id UUID PRIMARY KEY REFERENCES users(id) ON DELETE CASCADE,
-  current_streak_length INTEGER NOT NULL DEFAULT 0,
-  longest_streak_length INTEGER NOT NULL DEFAULT 0,
-  current_streak_last_date DATE NOT NULL
-);
-```
-
-## User Flow
-
-### For Authenticated Users:
-1. User completes daily puzzle
-2. Score automatically submitted to backend
-3. Streak calculated and updated
-4. Streak popup appears showing current streak
-5. User can dismiss popup and continue
-
-### For Non-Authenticated Users:
-1. User completes daily puzzle
-2. Login prompt modal appears
-3. User can sign in to start tracking or dismiss
-4. If dismissed, can still share results
-
-## Key Features
-
-✅ Automatic score submission on game completion
-✅ Streak tracking with proper date handling
-✅ Non-intrusive UI notifications
-✅ Encourages user engagement through login prompts
-✅ Handles edge cases (duplicate submissions, date boundaries, failed games)
-✅ No security vulnerabilities detected
-✅ Maintains existing game functionality
-
-## Testing Notes
-
-- All existing unit tests pass
-- Code review completed and feedback addressed
-- Security scan completed with no issues found
-- Manual testing recommended for:
-  - Completing puzzles while authenticated
-  - Completing puzzles while not authenticated
-  - Multi-day streak building
-  - Streak reset on missed days
-  - Failed game handling
-
-## Dependencies
-
-No new dependencies added. Uses existing packages:
-- next-auth (authentication)
-- postgres (database)
-- @mui/material (UI components)
-- motion (animations)

-# Quick Reference: Streak Tracking Feature
-
-## 🚀 Quick Start
-
-### For Developers
-
-1. **Database Setup** (Required before deployment)
-   ```sql
-   CREATE TABLE IF NOT EXISTS streaks (
-     user_id UUID PRIMARY KEY REFERENCES users(id) ON DELETE CASCADE,
-     current_streak_length INTEGER NOT NULL DEFAULT 0,
-     longest_streak_length INTEGER NOT NULL DEFAULT 0,
-     current_streak_last_date DATE NOT NULL
-   );
-   CREATE INDEX idx_streaks_user_id ON streaks(user_id);
-   ```
-
-2. **Environment Variables** (Ensure these exist)
-   - `DATABASE_URL` or `POSTGRES_URL` - PostgreSQL connection string
-   - `GOOGLE_CLIENT_ID` - Google OAuth client ID
-   - `GOOGLE_CLIENT_SECRET` - Google OAuth client secret
-   - `NEXTAUTH_URL` - Application URL
-   - `NEXTAUTH_SECRET` - NextAuth secret key
-
-3. **Testing Locally**
-   ```bash
-   npm install
-   npm run dev
-   ```
-   Visit `http://localhost:3000` and try completing a puzzle
-
-## 📋 Feature Overview
-
-### What Was Built
-
-| Component | Purpose | File |
-|-----------|---------|------|
-| Database Functions | Track and update user streaks | `app/lib/db/db.js` |
-| API Endpoint | Submit scores and update streaks | `app/api/submit-score/route.js` |
-| Streak Popup | Show streak after completion | `app/ui/streak-popup.js` |
-| Login Prompt | Encourage login for tracking | `app/ui/login-prompt-modal.js` |
-| Game Integration | Auto-submit scores | `app/ui/game-session.js` |
-| User Menu | Login/logout interface | `app/layout.js` |
-
-### How It Works
-
-```
-User completes puzzle
-    ↓
-Is user authenticated?
-    ↓                ↓
-   YES              NO
-    ↓                ↓
-Submit score    Show login prompt
-    ↓
-Update streak
-    ↓
-Show streak popup
-```
-
-## 🧪 Testing Scenarios
-
-### Manual Test Cases
-
-1. **Anonymous User Completes Puzzle**
-   - Expected: Login prompt modal appears
-   - Expected: Can dismiss and continue
-   - Expected: Can click "Sign In" to authenticate
-
-2. **New User First Completion**
-   - Expected: Streak popup shows "Streak Started! 1 Day"
-   - Expected: Popup is dismissable
-   - Expected: Score appears on leaderboard
-
-3. **User Completes on Consecutive Days**
-   - Day 1: Complete puzzle → "1 Day"
-   - Day 2: Complete puzzle → "2 Days"
-   - Day 3: Complete puzzle → "3 Days"
-   - Expected: Streak increments each day
-
-4. **User Misses a Day**
-   - Day 1: Complete puzzle → "1 Day"
-   - Day 2: Skip
-   - Day 3: Complete puzzle → "1 Day" (reset)
-   - Expected: Streak resets but longest is preserved
-
-5. **User Fails Puzzle (3 Strikes)**
-   - Complete with 3 strikes
-   - Expected: No popup shown
-   - Expected: Streak resets to 0
-   - Expected: Score shows as failed in leaderboard
-
-6. **Duplicate Completion Same Day**
-   - Complete puzzle once
-   - Try to complete again (refresh page, etc.)
-   - Expected: Streak doesn't change
-   - Expected: No duplicate submissions
-
-## 🐛 Common Issues
-
-### Streak Not Updating
-- Check database has streaks table
-- Verify user is authenticated
-- Check console for API errors
-- Ensure DATABASE_URL is set correctly
-
-### Login Not Working
-- Verify Google OAuth credentials
-- Check NEXTAUTH_URL matches your domain
-- Ensure NEXTAUTH_SECRET is set
-- Check NextAuth configuration
-

-## 💡 Tips for Customization
-
-### Change Popup Timing
-```javascript
-// In app/ui/game-session.js
-setTimeout(() => setShowStreakPopup(true), 500); // Change 500 to desired ms
-setTimeout(() => setShowLoginPrompt(true), 1000); // Change 1000 to desired ms
-```
-
-### Modify Streak Colors
-```javascript
-// In app/ui/streak-popup.js
-color: '#9333ea' // Change to any color
-border: '3px solid #9333ea' // Change border color
-```
-
-### Adjust Streak Logic
-```javascript
-// In app/lib/db/db.js, line 96
-// Current: Resets streak to 1 if not consecutive
-// To make it more forgiving, you could add grace periods
-```
-
-## 📊 Database Schema
-
-```sql
--- Main tables involved
-users (id, name, email, password)
-daily_scores (user_id, date, milliseconds)
-streaks (user_id, current_streak_length, longest_streak_length, current_streak_last_date)
-```
-
-## 🔐 Security
-
-- ✅ Authentication required for score submission
-- ✅ Server-side validation of user sessions
-- ✅ SQL injection prevention via parameterized queries
-- ✅ No sensitive data exposed in frontend
-- ✅ 0 vulnerabilities found in security scan
-
-## 🚢 Deployment Checklist
-
-- [ ] Create streaks table in production database
-- [ ] Verify environment variables are set
-- [ ] Test authentication flow works
-- [ ] Verify score submission works
-- [ ] Test streak calculation with real dates
-- [ ] Monitor error logs for issues
-- [ ] Test on mobile devices
-- [ ] Verify popup animations work smoothly

-# Database Migration for Streaks Table
-
-This document describes the database schema changes needed for the streak tracking feature.
-
-## Streaks Table Schema
-
-The following SQL should be executed to create the `streaks` table in the database:
-
-```sql
-CREATE TABLE IF NOT EXISTS streaks (
-  user_id UUID PRIMARY KEY REFERENCES users(id) ON DELETE CASCADE,
-  current_streak_length INTEGER NOT NULL DEFAULT 0,
-  longest_streak_length INTEGER NOT NULL DEFAULT 0,
-  current_streak_last_date DATE NOT NULL
-);
-
-CREATE INDEX idx_streaks_user_id ON streaks(user_id);
-```
-
-## Table Description
-
-- `user_id`: Foreign key reference to the users table. Primary key for this table.
-- `current_streak_length`: The user's current consecutive days streak.
-- `longest_streak_length`: The longest streak the user has ever achieved.
-- `current_streak_last_date`: The date of the user's last completed puzzle.
-
-## Notes
-
-- The streak is updated when a user completes a daily puzzle.
-- If a user completes a puzzle the day after their last completion, the streak increments by 1.
-- If a user misses a day, the current streak resets to 1 (or 0 if they fail).
-- The longest streak is preserved across streak resets.

-# User Experience Guide: Streak Tracking Feature
-
-This document describes how users will experience the new streak tracking feature.
-
-## For New/Anonymous Users
-
-### Before Signing In
-1. User plays and completes the daily puzzle
-2. A modal appears titled "Track Your Progress! 📊"
-3. The modal explains the benefits:
-   - 🔥 Start your streak
-   - 🏆 Compete on the leaderboard
-   - 📈 Track your progress over time
-4. User can either:
-   - Click "Sign In to Start Tracking" → Redirects to Google OAuth
-   - Click "Maybe Later" → Closes modal, can continue playing
-
-### User Menu (Header)
-- User icon in the top-right corner of the page
-- Click to open menu with "Sign in" option
-- Available at all times, not just after game completion
-
-## For Authenticated Users
-
-### After Signing In
-1. User's name appears next to the user icon in the header
-2. User menu now shows "Sign Out" option instead of "Sign in"
-
-### First Daily Puzzle Completion
-1. User completes the puzzle (matches all tiles correctly)
-2. Score is automatically submitted to the backend
-3. A streak popup appears with:
-   - 🔥 Fire emoji (animated scale-in)
-   - "Streak Started!" message
-   - "1 Day" in purple text
-   - "Keep it up! Come back tomorrow to maintain your streak."
-4. User clicks anywhere to dismiss the popup
-5. Can then share results as before
-
-### Subsequent Daily Completions
-
-#### Consecutive Days (Yesterday was completed)
-1. User completes today's puzzle
-2. Streak popup shows:
-   - "Streak Updated!" message
-   - Current streak count (e.g., "3 Days")
-   - Encouragement message
-
-#### After Missing a Day
-1. User completes a puzzle after missing one or more days
-2. Streak resets to 1
-3. Longest streak is preserved in the database
-4. Popup shows "Streak Started!" with "1 Day"
-
-#### Failed Puzzle (3 Strikes)
-1. User gets 3 strikes and fails the puzzle
-2. Current streak resets to 0
-3. No popup is shown (game failed)
-4. Score is recorded as null in the database
-
-### Streak Persistence
-- Streaks are tracked per user in the database
-- Current streak length is shown after each completion
-- Longest streak ever achieved is preserved
-- Last completion date is tracked to determine continuity
-
-## UI Components
-
-### Streak Popup
-- **Style**: Clean dialog with purple border, centered content
-- **Animation**: Scale-in effect for engagement
-- **Dismissal**: Click anywhere outside or on the popup
-- **Timing**: Appears 500ms after score submission completes
-
-### Login Prompt Modal
-- **Style**: Full-width dialog with purple border
-- **Features**: 
-  - Clear benefit explanations
-  - Highlighted feature list in purple box
-  - Two clear action buttons
-- **Timing**: Appears 1000ms after puzzle completion (for anonymous users)
-
-### User Menu
-- **Location**: Top-right corner of header
-- **Always visible**: Available on all pages
-- **States**:
-  - Not signed in: Shows user icon, menu has "Sign in" option
-  - Signed in: Shows user name + icon, menu has "Sign Out" option
-
-## Technical Details
-
-### Score Submission
-- Automatically triggered when game is finished
-- One submission per day (duplicates prevented)
-- Includes completion time for successful attempts
-- Includes null for failed attempts (3 strikes)
-
-### Streak Calculation
-- Checked against yesterday's date
-- Yesterday's completion → Increment streak
-- Same day completion → No change (duplicate)
-- Older than yesterday → Reset to 1
-- Failed game → Reset to 0
-
-### Privacy & Security
-- Only authenticated users can track streaks
-- Scores tied to user account via session
-- No sensitive data exposed in frontend
-- API validates authentication on every request
-
-## Error Handling
-
-### Network Errors
-- Failed submissions log errors to console
-- User can still share results
-- Score can be manually submitted later if needed
-
-### Database Errors
-- Handled gracefully with error responses
-- User sees normal game completion flow
-- Errors logged on backend for monitoring
-
-## Future Enhancements (Not in this PR)
-
-Potential additions that could build on this feature:
-- Display longest streak in user profile
-- Streak recovery (grace period for missed days)
-- Streak milestones and achievements
-- Social sharing of streak achievements
-- Streak leaderboard alongside time leaderboard
