# shared/

Cross-function Python modules — the local equivalent of an AWS Lambda Layer.

Anything in this directory is available to every function under
`functions/<name>/handler.py` as a regular import:

```python
# functions/sign_pdfs/handler.py
from shared import common_utils
```

The `shared/` directory is added to `sys.path` by the runner. For an AWS
deploy, you'd either:

1. Package it as a real Lambda Layer (preferred), and reference the layer ARN
   from each function's deploy spec, **or**
2. Vendor a copy into each function's deployment zip (simpler, less DRY).

Currently empty — no cross-function code yet. First candidate would probably
be a structured-logging helper once multiple functions need it.
