Run locally

Open index.html directly, or serve the directory with any static file server:

python3 -m http.server 8000

Publish with GitHub Pages

In the repository settings, choose Pages → Deploy from a branch → main → /. The intended public URL is:

https://castaliainstitute.github.io/castelia/

If a custom domain is later selected, add it in Pages settings and commit the generated CNAME file.

Working assumptions

The business plan treats Atlas and Mynah as Castalia products/devices that need persistent, international data connectivity. Pricing, carrier partners, regulatory structure, and launch markets are explicitly marked as validation items rather than settled facts.
