/* =====================================================
   INTELISKA - SHARED SITE DESIGN ("Light Premium")
   Used by every page EXCEPT the homepage (which has its own
   self-contained css/home.css) and the two dashboards.
   Provides: design tokens, reset, header, footer, buttons,
   cards, form fields, alerts, page-hero, scroll-to-top.
   Page-specific CSS (product.css, help.css, login.css ...)
   loads AFTER this file and only adds layout for that page.
