    # HRRR profile fetcher (Profile tab "Initialize from HRRR").
    # cfgrib needs the eccodes C library. Rather than requiring a system
    # install (brew install eccodes / apt install libeccodes-dev) we pull
    # it in from PyPI only. Current story (verified on PyPI, 2026-04):
    #   - `cfgrib` depends on `eccodes` (Python CFFI bindings, pure-Python
    #     wheel — no binary).
    #   - `eccodes` depends on `findlibs`, which looks for `libeccodes` in
    #     an installed Python package named `eccodeslib` first.
    #   - `eccodeslib` is ECMWF's new official binary-wheel package
    #     (macOS 13+ arm64/x86_64, manylinux_2_28 x86_64/aarch64, cp310..cp314).
    #   - `ecmwflibs` is the older bundle; stale since 2024 and missing
    #     cp312+. We keep it only as a Windows fallback since `eccodeslib`
    #     has no Windows wheels.
    # Result: `uv sync` / `pip install -e .` is enough on macOS and Linux.
