How Substr Polls Work Across Nostr Clients

We built polls as Nostr-native events, not as a closed backend feature.The poll itself is a normal Nostr post with extra tags like polloption, pollresults, and pollclosesat. Votes are separate Nostr events that reference the poll and include a poll_vote tag.

That means other clients can still receive and store the poll and vote data through relays. The only difference is rendering: clients that support these poll tags can show a real poll UI, while others will just show them as regular posts.
