Static site generator. Builds are transactional: staged output swaps in only on success, so a broken build never takes down the live site. Plugins run sandboxed in isolated Deno subprocesses, all permissions denied until granted.

Also has zero-config mode (one .md file -> site) and its own compiled templating language, Tau, with components, conditions, collections, includes, filters, and contextual escaping.
