 * by `HASNA_LOOPS_DATABASE_URL`) and the client's connection
 * (`file | api`, selected by `HASNA_LOOPS_API_URL` + `HASNA_LOOPS_API_KEY`).
 *
 * The client connects to a local SQLite file or to the server HTTP API. It
 * never opens Postgres directly: `HASNA_LOOPS_DATABASE_URL` is server-only and
 * is never used to connect from the client — at most its *presence* is
 * reported. A retired `HASNA_LOOPS_STORAGE_MODE` env is rejected with a hard
 * error (closed matrix: old mode env is never honored).
