/* ═══════════════════════════════════════════════════════════════════════════════
   CATEGORY NAVIGATION — LCARS STRIP DESIGN
   Shared base styles for all category navigation bars.

   Each nav sets its accent via CSS custom property:
     --cat-accent:       dark mode color (e.g. #FFAA00)
     --cat-accent-light: light mode color (e.g. #cc6600)

   Used by: admin_ops, admin_tools, dev_tools, creation_tools,
            business_tools, standalone_apps
