# Compose

> Premium message composer with @ mentions and / slash commands. A transparent textarea over a backdrop highlighter paints colored pills exactly behind matched tokens, with a caret-anchored, keyboard-navigable picker (DiceBear avatars for people, custom icons for commands), a rotating aurora focus ring, character counter ring, and a Send action. Dark mode and reduced-motion aware.
