/* NexusTrading — Notification Center
   A bell in the top bar with an unread badge, a dropdown panel listing
   entry/exit events as styled bubbles (read/unread), plus a transient
   "pop" bubble that slides in on each new event. All markup is injected
   by notifications.js; this file only styles it. Dark-terminal tokens
   come from app.css (:root). */
