/**
 * drizzle.sqlite.config.ts
 *
 * Drizzle Kit config for the SQLite variant. Mirrors `drizzle.config.ts` but
 * points at the SQLite schema directory and writes migrations to `drizzle-sqlite/`.
 *
 * The two dialects deliberately have separate migration histories - the SQL
 * differs (no enums, no jsonb operators, different default expressions) and a
 * single migration file can't satisfy both. Operators choose one DATABASE_URL
 * shape and stick with it; cross-dialect migration is a manual data export +
 * re-import, not something the migration runner attempts.
