   PURPOSE:
   Global visual system for the Vixly Control Plane.

   RESPONSIBILITIES:
   - Define framework defaults
   - Define base reset
   - Define Control Plane shell styling
   - Define sidebar, menu, topbar, public layout, and login visuals
   - Provide responsive behavior

   IMPORTANT NOTES:
   - ControlPlane intentionally differs from Operations Plane
   - Shell/layout styling is intentionally global
   - Sections are numbered for easier future reference
   - Duplicate login/public styles have been removed
