/* Nexus Resolve — design system layer.
   Loaded after Tailwind CDN so plain-element rules override the browser default.
   Tailwind utility classes still drive layout/spacing — this file owns:
     1. Design tokens (CSS variables, dark-mode aware)
     2. Baseline rendering for unstyled HTML elements (Django `{{ field }}` output)
     3. Polish: focus rings, scrollbars, animations
