-- Incoming typing animation (brief "..." bubble before message appears)
---------------------------------------------------------------------------
-- This is handled visually: when a whisper arrives, we briefly show a
-- typing bubble before displaying the actual message. Since we can't
-- predict incoming messages, we skip this for now and just add a subtle
-- "received" animation (message slides in). The typing indicator is
-- primarily for the outgoing side.
--
-- Future: Could use hidden addon messages (C_ChatInfo.SendAddonMessage)
-- with registered prefixes for iChat-to-iChat typing, but that requires
-- both parties to have the addon.
