Looking at the task, I need to create a Python program that:
1. Reads a binary `.tza` file containing frames
2. Outputs a Tiny-ANSI byte stream that efficiently reproduces each frame
3. Stays within a tight byte budget (`max_bytes`)

The key insight is that I should only output the changes between frames (delta encoding), using cursor positioning to update only the cells that changed.

Let me start by examining the input file to understand its structure:

```json
{
  "analysis": "I need to create a Python program that reads a binary .tza file and outputs a Tiny-ANSI stream. The program must be efficient to stay within max_bytes budget. First, let me examine the input file to understand its structure.",
  "plan": "1. First, examine the frames.tza file to understand its structure and size\n2. Create the termzip_ansi.py program that implements delta encoding\n3. Test the program with the provided file",
  "commands": [
    {
      "keystrokes": "ls -la /app/\n",
      "duration": 0.1
    },
    {
      "keystrokes": "xxd /app/frames.tza | head -20\n",
      "duration": 0.1
    },
    {
      "keystrokes": "wc -c /app/frames.tza\n",
      "duration": 0.1
    }
  ]
}
```
