  * @param ruleContext The ESLint rule context.
  * @param orderingStrategy The strategy to use for ordering CSS properties ('alphabetical', 'concentric', or 'userDefinedGroupOrder').
  * @param userDefinedGroupOrder An optional array of property groups for the 'userDefinedGroupOrder' strategy.

- * This function sets up visitors for the following cases:
- * 1. The fontFace and globalFontFace functions.
- * 2. Style-related functions: 'keyframes', 'style', 'styleVariants'.
- * 3. The 'globalStyle' and 'globalKeyframes' function
- * 4. The 'recipe' function
- *
- * Each visitor applies the appropriate ordering strategy to the style objects in these function calls.
