/* ==========================================================================
   DevOpsSchool — Shared UI Theme  (v3 — Courses-page design language)
   --------------------------------------------------------------------------
   Modeled on https://www.devopsschool.com/courses/ :
     • Dark navy TOP UTILITY BAR  (email · phone · currency · social · auth)
     • Clean WHITE MAIN NAVBAR    (DS logo · compact menu · rounded active pill)
     • Dark gradient/grid HERO    (headline · search box · category pills)
     • Dark enterprise FOOTER     (consistent with hero)
     • Floating WhatsApp CTA
   --------------------------------------------------------------------------
   COEXISTENCE: authored Tailwind-first with `preflight:false` + `container:false`.
   No global reset; every rule is scoped to #ds-navbar / #ds-footer / #ds-whatsapp
   or namespaced `.ds-*` helpers, so legacy Bootstrap-4 pages stay intact.
