Building every page into a ready HTML file at deploy time, so requests are served as files from a CDN with no application server involved in the response.
It is the fastest and cheapest way to serve content that does not change per visitor, and the most resilient: there is no database or backend that can fail under a traffic spike.
We generate statically wherever content allows and refresh pages incrementally when the source data changes, so editors see updates within seconds without a full rebuild of the site.
