deploy.yml

name: Deploy to GitHub Pages

# Builds the Vite project and publishes ONLY the compiled dist/ output —
# not the raw source. This is the piece that was missing: GitHub Pages
# is a static file host, it doesn't run `npm run build` for you. Without
# this, index.html's <script src="/src/main.jsx"> gets served as a raw
# .jsx file with the wrong MIME type, and the browser refuses to run it
# as a module — that's the exact "Expected a JavaScript-or-Wasm module
# script" error this fixes.
