/* estudio.css — landing de estudios del Lab (Edgebound Labs).
   Scope estricto .est-* para no tocar blog, glosario ni guias.

   DOS TEMAS. El panel de ajustes alterna body.hero-light en tiempo de ejecucion,
   asi que cada componente define sus colores OSCUROS por defecto y los CLAROS bajo
   .hero-light, con propiedades reales. No se usan variables intermedias: el motor
   no repinta de forma fiable un cambio de token heredado al cambiar una clase
   ancestro (documentado en DESIGN_SYSTEM.md y en styles.css). */
