name: Deploy to GitHub Pages

# Builds the static site and publishes it to GitHub Pages on every push to
# main. The RF engine ships as committed WebAssembly (src/engine/generated/),
# so this needs no Emscripten — just a frontend build. Correctness (engine
# rebuild diff, type check, golden tests) is gated separately by ci.yml.
#
# One-time setup in the repo: Settings → Pages → Source = "GitHub Actions".
