# Summary of Changes - Steam Integration & Icon System

## Date: November 9, 2025

---

## 1. Icon System Implementation

### Created Icon Directory Structure
```
images/icons/
├── items/       # Item icons (weapons, armor, consumables)
├── ui/          # UI elements (buttons, menus)
├── status/      # Status indicators (HP, stamina)
└── actions/     # Action icons (attack, defend, flee)
```

### Icon Specifications
- **Format:** SVG (recommended) or PNG
- **Size:** 64x64px standard, 128x64px large, 32x32px small
- **Naming:** kebab-case matching item IDs (e.g., `iron-sword.svg`)
- **Usage:** Icons referenced via `icon_path` field, emojis kept as fallback

### Documentation
- Created `/images/icons/README.md` with full guidelines

---

## 2. Database Migration - Steam Support

### Migration Script: `migrate_steam_support.py`

**Added Columns:**
```sql
ALTER TABLE players ADD COLUMN:
- steam_id VARCHAR(255) UNIQUE  -- Steam user ID
- email VARCHAR(255)             -- Required for web users
- premium_expires_at TIMESTAMP   -- NULL = premium, timestamp = trial end
- account_type VARCHAR(20)       -- 'web', 'steam', 'telegram'
```

**Removed:**
- `telegram_id` column (deprecated, no longer supporting Telegram)

**Indexes Created:**
- `idx_players_steam_id` - Fast Steam ID lookups
- `idx_players_email` - Email verification/login

**Constraints:**
- `CHECK (account_type IN ('web', 'steam', 'telegram'))`
- Steam ID must be unique
- Email used for password reset and communications

### Migration Results
```
✅ Added columns successfully
✅ Created indexes
✅ Updated 5 existing users to 'web' account type
✅ Dropped telegram_id column (no legacy users found)
✅ Added account_type constraint
```

## 3. Premium System Design

### Account Types

**Web Users:**
- Email/password registration
- Free trial: Level 1-10
- Premium: Full access after payment

**Steam Users:**
- Auto-authenticated via Steam
- Always premium (owns game on Steam)
- No email/password needed

### Premium Logic

**Premium Status:**
```python
premium_expires_at == NULL  # Lifetime premium (purchased or Steam)
premium_expires_at > now()  # Active trial/subscription
premium_expires_at < now()  # Expired, back to free tier
```

**Restrictions for Non-Premium (Level 10+):**
- ❌ No XP gain after level 10
- ✅ Full map access (naturally gated by difficulty)
- ✅ Can party with premium players
- ✅ All items/crafting/combat features

## 4. UI Fixes - Equipment Slots

### Problem
Equipment slots changed size when items equipped due to emoji + button content.

### Solution
**Fixed dimensions in `Game.css`:**
```css
.equipment-slot {
  min-height: 100px;
  max-height: 100px;
  height: 100px;
  overflow: hidden; /* Prevent content overflow */
}
```

**Reduced button sizes:**
```css
.equipment-action-btn {
  padding: 0.2rem 0.4rem;
  font-size: 0.75rem;
  white-space: nowrap;
}

.equipment-emoji {
  font-size: 1.2rem; /* Reduced from 1.5rem */
}
```

**Result:** All equipment slots now same size, whether empty or filled.

## 5. Comprehensive Planning Document

### Created: `STEAM_AND_PREMIUM_PLAN.md`

**Contents:**
1. **Account System** - Database schema, account types
2. **Distribution Channels** - Web, Steam, Standalone
3. **Asset Bundling Strategy** - Hybrid approach for desktop
4. **Steam Integration** - Steamworks SDK, authentication flow
5. **Build Variants** - Web vs Steam vs Standalone configs
6. **Premium Enforcement** - XP restrictions, helper functions
7. **Implementation Roadmap** - 5-phase plan
8. **Tech Stack Recommendations** - Tauri for desktop client
9. **Cost Estimates** - $100 Steam fee + payment processing
10. **Monetization Strategy** - Pricing options

**Key Decisions:**
- **Desktop Framework:** Tauri (Rust + WebView)
  - Smaller than Electron (~5MB vs 100MB+)
  - Better security
  - Native performance
  
- **Asset Strategy:** Hybrid bundling
  - Bundle core assets (~50MB)
  - Lazy load rare content
  - Cache everything locally

- **Pricing Model:** Steam-paid, web-freemium
  - Steam: $14.99 (full game)
  - Web: Free trial to level 10, $4.99 upgrade

## Questions for Product Decision

1. **Free Tier Level Cap:**
   - Current: Level 10
   - Alternative: Level 5? Level 15?
   - Recommendation: Level 10 (enough to hook players)

2. **Premium Pricing:**
   - Web upgrade: $4.99? $9.99?
   - Steam full game: $14.99? $19.99?
   - Recommendation: $4.99 web, $14.99 Steam

3. **Email Verification:**
   - Required immediately on registration?
   - Or allow play, verify for premium upgrade?
   - Recommendation: Optional initially, required for premium

4. **Steam-Exclusive Features:**
   - Any features only for Steam users?
   - Or complete parity with web premium?
   - Recommendation: Complete parity (fair for web buyers)
