-- JSONL streaming: rdjl reads a JSONL file line by line and returns
-- L (R _ t) — a list of per-line parse results. Empty lines are skipped,
-- so log files with stray blank lines parse cleanly. Each entry is
-- wrapped in a Result so a single malformed line doesn't poison the
-- whole stream.
-- Hydrate a JSONL fixture, then count the parsed entries. In a real
-- pipeline rdjl is used on a file produced by a log shipper or another
-- process; here we generate one in-place so the example is hermetic.
