   Hixel My — Custom styles (loaded AFTER Bootstrap 5 CDN)

   Hixel platform UI is dark-first. Tokens follow the brand book at
   /docs/hixel-brand-book.md. Bootstrap handles: grid, typography, forms,
   buttons, tables, cards, alerts, badges, breadcrumbs, navbar, utilities.

   This file adds: admin shell layout, sidebar nav, topbar, and Hixel-specific
   component styles that don't exist in Bootstrap.
