Added these settings to my local config and none of them worked. I have no clue how to get CSS working with the CSS (Naomi) syntax highlighting.

This project's default settings file says it looks for the .tmLanguage file, but none exists. Naomi uses the newer .sublime-syntax format and that's possibly why it's not showing up.

{
  "codeintel_syntax_map":
  {
    "naomi.css3.sublime-syntax": "CSS",
    "naomi.css3": "CSS",
    "CSS (Naomi)": "CSS",
    "CSS Naomi": "CSS",
    "naomi css3": "CSS",
    "naomi": "CSS"
  }
}
