## Workarounds

1. **** (95% success)
   ```
   Ensure base.html exists in templates directory and set TEMPLATES = [{'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [BASE_DIR/'templates']}]
   ```
2. **** (90% success)
   ```
   Use {% extends 'app/base.html' %} and ensure app/templates/app/base.html exists.
   ```

## Dead Ends

- **** — Setting TEMPLATE_DIRS incorrectly doesn't find the template. (60% fail)
- **** — Using absolute path without adding to DIRS still fails. (40% fail)
