# Convenience wrapper for `cargo bench` with sensible defaults and
# criterion-compatible filtering.
#
# Usage:
#   ./bench.sh                  # quick run (warmup 1s, measurement 2s)
#   ./bench.sh full             # criterion defaults — slower, more accurate
#   ./bench.sh parse            # run only parse-related benches
#   ./bench.sh render           # run only render benches
#   ./bench.sh "parse|render"   # any criterion regex
#
# Criterion stores the last baseline in target/criterion/ and
# automatically diffs against it on the next run.
