/* ============================================================
   base.css  —  SHARED STRUCTURE & COMPONENTS
   ------------------------------------------------------------
   Everything every page shares: reset, layout container,
   the fixed header + navigation + mobile menu, the footer,
   buttons, section rhythm, scroll-reveal, and the home hero.

   Page-specific section styling can live in its own file
   (e.g. css/home.css) so this file stays reusable site-wide.
