# Governed Construction Boundary

> Route all DOM creation through one governed factory that resolves a node spec of shape `{ el, variant, size, gap, tone, measure, layout, class, on, children }` against the type, handler, and component registries, maps each axis key to its `data-*` attribute, treats `class` as a gated hook (icon-font glyph, `u-*` utility, or `c-*` component — never bespoke, never appearance), throws on any unknown type, handler, or component, and refuses an inline `style` attribute.
