BEM + SASS Skill

This skill provides comprehensive guidance for writing, auditing, and architecting SASS/SCSS following the BEM (Block-Element-Modifier) methodology as defined at getbem.com.

It serves two modes:

1. Generator mode — write new SCSS code following BEM conventions.
2. Auditor mode — review existing SCSS code and report BEM violations.
