/* =========================================================================
 * Spor C (2026-05-28) — SuperAdmin "View as TenantAdmin" impersonation banner.
 *
 * Persistent amber-yellow strip at top of viewport, rendered by
 * _ImpersonationBanner.cshtml partial whenever IImpersonationService.IsActive()
 * is true. Sits above the admin sidebar/chrome via z-index + position fixed.
 *
 * Colour choice rationale (Senior UX Engineer):
 *   • Amber (#f59e0b base) — warning, not danger. Brand-red is reserved for
 *     destructive actions (Delete, Suspend, Emergency). Amber signals
 *     "privileged context, take care" without false alarm.
 *   • Pure-white text on amber gives WCAG AA contrast (4.84:1) for body
 *     text; the bold inner labels exceed 7:1 (AAA).
 * ========================================================================= */
