/* ============================================
   CodeCraftedApps — Brand Core
   Design tokens + components shared by every section of the site.
   Load FIRST on every page, before the section stylesheet:
     <link rel="stylesheet" href="css/brand-core.css?v=1">
     <link rel="stylesheet" href="css/style.css?v=N">   (or the section's)
   Section stylesheets may override tokens (brew's amber, the
   platform accents) — they load after this file, so they win.
   Reference: /style-guide.html
