"""Capture an initial baseline from a trusted manual run.

Usage (one-shot, MI300X host only):
    python3 tests/benchmarks/publish_baseline.py \
       --input  tritonbench_results.json kernelbench_results.json \
       --output benchmarks/baseline/mi300x_baseline.json

Subsequent baseline bumps are explicit PRs that replace the file —
the nightly workflow never writes to this path.
