What the armillary is
A router that composes what a workspace declares. A bare clone is already a working host.
Placeholder. This essay introduces the armillary as a router rather than a framework: it composes whatever a workspace declares in modules.toml and assumes nothing by default. The load-bearing point for a first-time reader is that a bare clone with no modules is already a working host — composition is additive, and there is no configuration to get wrong before the thing runs.
