How It Works

┌─────────────────────────────────────────────────────────────┐
│  1. LOAD LEARNINGS from LEARNINGS.md                        │
│     - Apply positive patterns (+3, +1 boosts)               │
│     - Include negative patterns in exclusions (-1, -3)      │
├─────────────────────────────────────────────────────────────┤
│  2. GENERATE OPTIONS (A and B)                              │
│     - Option A: Base prompt with current learnings          │
│     - Option B: Base + additional style modifiers           │
│     - Save to: public/images/generated/training/            │
├─────────────────────────────────────────────────────────────┤
│  3. CREATE COMPARISON GRID                                  │
│     - Side-by-side A|B image for easy comparison            │
├─────────────────────────────────────────────────────────────┤
│  4. USER SELECTS                                            │
│     - A, B, or Neither with feedback                        │
├─────────────────────────────────────────────────────────────┤
│  5. UPDATE LEARNINGS                                        │
│     - Boost winning patterns                                │
│     - Record negative patterns from feedback                │
│     - Persist to LEARNINGS.md                               │
├─────────────────────────────────────────────────────────────┤
│  6. PUBLISH (optional)                                      │
│     - Push to GitHub → Cloudflare Pages                     │
│     - Get public URL for mobile access                      │
├─────────────────────────────────────────────────────────────┤
│  7. ITERATE until satisfied                                 │
