   TallerPro — Estilos "industrial / taller" (ADR-024) sobre Bootstrap 5.3.
   Mobile-first: la base es el teléfono del mecánico; el escritorio mejora.
   El reskin se hace redefiniendo las variables por componente de Bootstrap
   (--bs-*) para no recompilar Sass, más el shell propio (sidebar/navbar/KPIs).
