   NEXORA DESIGN SYSTEM — Phase 3
   Loaded in addition to /assets/css/site.css on new Phase 3 pages
   only. Reuses site.css's :root tokens (colors, fonts) — does not
   redefine them, to guarantee zero visual drift from the existing
   brand. Adds the component vocabulary Phase 3 pages need that
   site.css doesn't yet have: badges, tables, form inputs, alerts,
   timeline, dashboard widgets, chart placeholders, and formal
   spacing + motion scales.
