What you're building

You're building a full mini polling platform: create a poll with a question and custom answer options, vote on it, and watch a live results dashboard with animated percentage bars -- all backed by localStorage so multiple polls persist between visits. This is the same core feature behind tools like Slido or Mentimeter, built from scratch with nothing but arrays, objects, and CSS width transitions.
