/* ============================================================
   Market Insights — Centralized Alerts (Iter 25U)
   Bell in mi-topbar-right + right-anchored overlay panel.
   Follows market-insights-ux-ui skill:
     - 44x44 touch targets
     - z-index 9500 (page-overlays tier)
     - -popover suffix on the panel (global mobile clamp applies)
     - design tokens only (local --mi-alerts-* helpers below)

   Iter 25AU: deeper blue-grey panel surface so the notification
   tray reads as a distinct, slightly-cool surface vs the standard
   --bg-card. All shades sit within the existing dark theme; no
   new global tokens introduced.
