Detailed Description

Logger that writes one line per record to std::cerr.

Line layout: YYYY-MM-DDThh:mm:ss.mmmZ LEVEL [tid] [file:line] message. The minimum level is held in a lock-free atomic; a mutex serializes the whole-line write so concurrent records never interleave. Pure standard library – always compiled, regardless of ICEBERG_SPDLOG.
