   Complere command-center stylesheet
   --------------------------------------------------------------------------
   Original visual system inspired by the look and feel of a modern public
   university brand (deep purple on white, generous whitespace, clean sans
   typography, a top nav shell and a structured footer), reworked for a dense
   authenticated admin surface rather than a marketing site. No third-party
   assets, fonts-as-files, logos, or wordmarks are used; every value here is
   original. All colors were contrast-checked to meet WCAG AA.
