## What Was Changed

### Automatic Conversions Applied:
1. **Auto-detection code injection** - Added `find_covid_fasta()` function to each file
2. **Genome path updates** - Replaced `ecoli_k12.fasta` with auto-detection calls
3. **Text replacements** - Changed all "E. coli" references to "SARS-CoV-2"
4. **Visual enhancements** - Updated background color to `#000011` for better contrast
5. **Informational output** - Added genome info to main execution block

### Genome Auto-Detection
All files now include:
```python
def find_covid_fasta():
    """Automatically find the COVID-19 FASTA file in the ncbi_dataset"""
    import glob
    possible_paths = [
        r"ncbi_dataset\data\GCF_009858895.2\*.fna",
        r"ncbi_dataset\data\GCA_009858895.3\*.fna",
        r"ncbi_dataset\data\*\*.fna",
    ]
    for pattern in possible_paths:
        files = glob.glob(pattern)
        if files:
            return files[0]
    raise FileNotFoundError("Could not find COVID-19 FASTA file")
```
