   Reactions — ReactionBar component (Facebook-style emoji picker)

   Two visual pieces:
     1. .reaction-bar — inline pill containing the "React" button,
        the small "•••" opener, and (when reactions exist) an
        aggregate strip showing top emojis + total count.
     2. .reaction-picker — floating 6-emoji palette that appears
        above the bar on hover / click.
