name: Deploy demo to GitHub Pages

# Publishes the bundled simulation UI (HTML + the linked Scala.js bundle) to
# GitHub Pages. The page auto-detects that the http4s backend isn't reachable
# from a static host and flips the backend toggle to "simulation" — so the
# deployed demo is fully self-contained, no server required.
