/* ============================================================================
   Athena Deploy Center — Responsive overrides (Phases 32-36)
   ----------------------------------------------------------------------------
   Extracted VERBATIM from site.css, where this block already sat AFTER every
   page section it overrides. It is linked LAST in _Host.cshtml so that ordering
   is preserved.

   Safe to move past the three site.css sections that used to follow it (Agent
   Log Viewer, Alert count badges, Monitor condition builder): they share no
   selector with anything in here, so nothing changes hands in the cascade.
