"""Maps OpenCV namespace paths to the Elixir module names they emit as.

Most OpenCV namespaces map mechanically (`cv::Foo` -> `Evision.Foo`) but a
handful of cases need hand-picked overrides for ergonomics:

  * Abbreviations / acronyms that look ugly title-cased (`dnn` -> `DNN`,
    `ml` -> `ML`, `ccm` -> `CCM`).
  * Multi-word names where the natural splits aren't on `_`
    (`ximgproc` -> `XImgProc`, signaling "extension" + "img" + "proc").
  * Nested enum types whose containing class is itself overridden.

This dict was previously inlined inside `gen2.add_const`; it is consulted
once per parsed enum so re-creating it on every call wasted memory.
