/* ENSFácil · Design system v2 — «Claro editorial»
   Escuela: portfolio editorial minimalista (ref. pleurat.com / Familia
   monocromo suizo del catálogo Awwwards: crema + tinta + un acento).
   Regla nº1: pocos mecanismos, bien ejecutados — tipografía protagonista,
   metadatos mono con códigos del ENS, footer con peso. El resto, silencio.
   Las páginas antiguas conservan sus clases: aquí cambian los valores. */
