The product page is deployed with GitHub Actions from the main branch. The public URL is:
https://masarray.github.io/ARNetDiscovery/
The workflow uploads the docs folder as the Pages artifact root, so docs/index.html becomes the public site root. The repository does not need a gh-pages branch or branch-based Pages publishing.
In GitHub, open:
Settings -> Pages -> Build and deployment -> Source -> GitHub Actions
After that, every push to main that changes docs/** or the Pages workflow can deploy the product page.
