/* ==========================================================================
   identity-guard.css — transient "your session changed" overlay
   --------------------------------------------------------------------------
   Shown by /js/identity-guard.js for a beat before it force-reloads a tab
   whose cookie identity changed in another tab (a login, logout, or account
   switch elsewhere in the same browser). Styled in the ProEstimate
   paper/charcoal/orange system so it reads as an intentional part of the app,
   not a crash or a random refresh.

   Tokens come from pe-design.css (loaded globally in App.razor); each var has
   a hard-coded fallback so the overlay is self-sufficient even if a page
   somehow renders without that stylesheet.

   High z-index + id selectors keep it above all page chrome. The element is
   injected/removed by the guard script, so it only exists for ~0.75s.
