/* =============================================================================
   Blazor Reconnection Overlay
   
   Replaces the default tiny "Reconnecting..." bar with a full-screen overlay
   designed for non-technical poll workers on iPads at election day poll sites.
   
   Blazor manages the #components-reconnect-modal element automatically,
   toggling CSS classes:
     - components-reconnect-show     → Disconnected, retrying
     - components-reconnect-hide     → Connected (hidden)
     - components-reconnect-failed   → Gave up retrying
     - components-reconnect-rejected → Circuit expired on server
