/**
* ScssClassScope_CodeQualityRule - Enforces SCSS class scoping convention
*
* SCSS files in rsx/app/ and rsx/theme/components/ must be fully enclosed in a
* single top-level class selector that matches their associated JavaScript class
* or Blade view.
*
* Rules:
* - rsx/app/**\/*.scss → must match a Component subclass (action/layout/component) or Blade @rsx_id
* - rsx/theme/components/**\/*.scss → must match a Component subclass or Blade @rsx_id
* - Filename must match the associated file's filename (different extension)
* - EXCEPTION: Supplemental SCSS files may have different filenames if a primary SCSS file
* (with matching filename) already exists for that wrapper class. This allows splitting
* large stylesheets (e.g., by breakpoint or feature).
* - Other SCSS files are not validated by this rule
*
* Additionally checks for nested component selectors - styling another component from within
* this component's SCSS creates hidden coupling and scatters styles across files.
*
* NO EXEMPTIONS: Files in these paths MUST follow the convention. If a file truly
* cannot follow the pattern, it must be moved outside these directories (e.g., to
* rsx/theme/base/) but this requires explicit developer approval.
