/* ============================================================
   VBI-IMP-U — PersonaSwitcher + ImpersonationBanner styles
   ------------------------------------------------------------
   Breakpoints: 360 / 481 / 768 / 1024 / 1440.
   - <481px: PersonaSwitcher renders as a bottom-sheet overlay.
   -  >=481: anchored dropdown panel.
   Banner is sticky-top, full width, z-index above the alert
   strip but below modal dialogs. Touch targets >=44px.
   Banner padding is compact — keeps push-down under 44px.
