/* ============================================================
   ZWIP · Changelog — estilos del cuerpo (hero + timeline + mocks).
   Portado del diseño de referencia, pero REMAPEADO a los tokens del
   sitio (home-v2.css: --p-bg / --p-teal / Space Grotesk) para que sea
   el mismo zwip y no el mockup suelto. Nav y Footer son los reales
   (home-v2.css), así que acá NO se definen .nav/.logo/.btn/.footer.
   Todo va namespaced bajo .changelog-page para no chocar con el home.
