# We only run benchmarks on pull requests to catch accidental breakage early.
# We don't run on push to main/release because benchmarks aren't actively used
# for anything right now — if they break post-merge it's not a release blocker.
# If we ever care about benchmark results over time, that would be a separate
# workflow on main that tracks performance trends, not this one.
