## Data Source Architecture

- Mailbox JSON index files and split parts are fetched via `/mail/:mailbox/index*.json` and redirected at the CDN layer to:
  - `https://huggingface.co/datasets/enronarchive/mail`
- Attachment file requests under `/mail/:mailbox/attachments/*` are also redirected to the same dataset.
- This repository is now focused on viewer app code and static assets, while mailbox payload data is hosted externally.
