UI components

Emoji reaction chips with a picker; reacting bursts a few copies of the emoji and rolls the count.

Up / down vote control where the score rolls in the vote’s direction and the chosen arrow fills.

A poll that reveals results after you vote: bars grow to their share, your pick is ticked, the leader is bold.

A compact chat: your message slides up from the composer, shows Sent then Read, and a typing indicator precedes replies.

A share card: copy the link with a tick, pick access (anyone / team / invite-only), and share targets as a row of icons.

Threaded comments with collapsible replies, inline reply boxes that open under the comment, and like counts.
