"""GQA attention kernels, panel runners, and helpers (internal subpackage).

The bench-package auto-discovery in ``kernbench.benches.registry``
skips subpackages, so this folder is not audited for ``@bench``
decorators. The only public-facing GQA bench is
``kernbench.benches.milestone_1h_gqa`` (umbrella that drives all
panels by importing this subpackage's ``gqa_decode_long_ctx_4cases``
and ``gqa_prefill_long_ctx_4cases`` modules).
