+//! Benchmarks for writer per-column overhead at high column cardinality.
+//!
+//! These benchmarks measure the structural cost of creating, writing, and
+//! closing a parquet file with many columns while keeping actual data
+//! encoding negligible (1 row per column). This isolates overhead such as
+//! `WriterProperties` per-column lookups, `GenericColumnWriter` allocation,
+//! and metadata assembly.
