How do I show unread message badges?
Store unreadCount in the conversation. In ChatList, show a badge with the count if unreadCount > 0. When a chat is opened, emit messages:read to mark as read and reset the count. Listen for message:received to refresh the chat list and update unread counts.

Create three spans with CSS animation that changes opacity (0.3 → 1 → 0.3) with staggered delays (0s, 0.2s, 0.4s). Show the component when isTyping is true (from Socket.io typing:update event). Hide it when typing:stop is received or after a timeout.
