   SAMERO MAGNETS — Design system v2
   Concepto: la paleta viene del propio objeto del negocio —
   el par de polos de un imán (norte / sur). Nada de acentos
   decorativos: rojo y azul acero son literalmente la polaridad.
   Type: Big Shoulders Display (foundry/industrial) + IBM Plex Sans + IBM Plex Mono
