-- Module      : Harmonic.Config
-- Description : Connection constants and file paths for Neo4j and corpus data
--
-- Centralised configuration for Neo4j database connection (URI, credentials)
-- and YCACL corpus file paths used during data ingestion.
--
-- theHarmonicAlgorithm is a local-first tool. Neo4j runs on localhost via
-- docker-compose, which configures the same credentials shown here. There is
-- no network exposure — these are docker defaults, not secrets.
-- To start Neo4j: @docker compose up -d neo4j@

    -- * Neo4j connection
    neo4jUri, neo4jUser, neo4jPassword,

    -- * Corpus paths
