  ANGLE SUMMARY:
  ============================================
  
  Step 1: 0°  → 20°  (slow)
  Step 2: 20° → 0°   (slow)
  Step 3: 0°  → 50°  (medium - tongue fully out)
  Step 4: 25° ↔ 45°  (shaking x10)
  Step 5: 50° → 20°  (partial close)
  Step 6: 20° ↔ 50°  (open/close x2)
  Step 7: 22° ↔ 48°  (shaking x15, faster)
  Step 8: 50° → 0°   (fast emergency close)
  
  Max angle: 50°
  Min angle: 0°

  FROG DESIGN NOTES:
  ============================================
  
  - Paint box GREEN
  - Cut mouth shape on the door
  - Glue RED PAPER TONGUE inside the mouth
  - Attach two big paper eyes on top
  - Tongue moves with the door (servo controls jaw)
