"""
Seeds the employee roster into DynamoDB from config.json.

Usage: python3 scripts/seed_roster.py

Each employee needs: name, email, and slack_user_id (for DM reminders).
To find Slack user IDs, use the Slack API:
  curl -s -H "Authorization: Bearer $TOKEN" \
    "https://slack.com/api/users.lookupByEmail?email=name@seahavenind.com" \
    | jq .user.id
