/* ==========================================================================
   AI Infrastructure Monitor — V2 presentation styles.
   Every rule is scoped to .v2-app, body.v2-mode, or the new .ver-switch
   chrome so nothing here can restyle V1 elements. V1 (site.css/app.js)
   stays untouched; V2 renders into its own #v2App mount and only activates
   when body has the v2-mode class (hash route #/v2).
