Now I understand the challenge better:
- Average 131 changes per frame
- Budget: 57.5 bytes per frame
- Need ~0.44 bytes per changed cell

The key is to use single-byte control characters (CR, LF, BS) instead of escape sequences where possible. Let me analyze the change patterns more:

```json
{
  "analysis": "With 131 average changes per frame and only 57.5 bytes budget per frame, I need to use ~0.44 bytes per changed cell. Escape sequences are too expensive. I must use CR (0x0d), LF (0x0a), BS (0x08) which are only 1 byte each.",
  "plan": "1. Analyze change patterns to see if changes are row-aligned\n2. Implement a strategy that uses CR+LF to move to rows and minimal cursor movements within rows",
  "commands": [
    {
      "keystrokes": "python3 -c \"\nimport struct\nwith open('/app/frames.tza', 'rb') as f:\n    magic = f.read(4)\n    width, height = struct.unpack('<HH', f.read(4))\n    n_frames, max_bytes = struct.unpack('<II', f.read(8))\n    frames = [f.read(width * height) for _ in range(n_frames)]\n\nprev = b' ' * (width * height)\ntotal_runs = 0\ntotal_run_cells = 0\nfor frame in frames:\n    in_run = False\n    for i in range(width * height):\n        if prev[i] != frame[i]:\n            if not in_run:\n                total_runs += 1\n                in_run = True\n            total_run_cells += 1\n        else:\n            in_run = False\n    prev = frame\n\nprint(f'Total runs of consecutive changes: {total_runs}')\nprint(f'Total changed cells: {total_run_cells}')\nprint(f'Average run length: {total_run_cells / total_runs:.2f}')\nprint(f'Average runs per frame: {total_runs / n_frames:.2f}')\n\"\n",
      "duration": 2.0
    }
  ]
}
