Headless delivery and zone-aware assembly work together

Spectare now surfaces two related capabilities on its features page: headless delivery and zone-aware assembly. Headless means the assembly API returns clean JSON that your own design system renders, with no Spectare markup or component shell imposed on the output. Zone-aware means the page declares which zones it actually renders and the component budget follows those declarations rather than filling slots that are not present.

The two capabilities compose naturally. A headless integration passes a zones array in the request body naming only the zones the page will render, and the engine restricts assembly to those zones. The result is a JSON payload containing only the components your design system needs to handle, with no orphaned slots to discard.

This matters most when Spectare is dropped into a design system that owns its own component hierarchy. The assembly engine does not need to know about your component library: it returns atoms mapped to zone names, and your renderer decides how each zone looks. The same atom library that serves your Next.js SSR path and your WordPress plugin serves the headless path without any duplication.

Both options are listed alongside the script tag, WordPress plugin, Next.js SSR, and direct REST API on the Spectare features page, so teams evaluating integration paths can compare them in one place.
