Coba TIWA — Water Treatment Engineering, Tested in the Open
A scratch subdomain where new layouts ship before they reach the money site.
Why this subdomain exists
Coba is the staging ground for layout experiments. Every block here is built with native core blocks only and the strict Frost design tokens — no third-party namespaces, no arbitrary hex codes, no inline style exceptions.
What we test here
Native blocks only
Every layout uses core/group, core/columns, core/heading, core/paragraph and core/buttons. No third-party namespaces.
Frost tokens, strictly
Colors are limited to base, contrast, primary, secondary and neutral. Font sizes stay inside small/medium/large/x-large/xx-large.
Dual declaration
Every styling class on an element has its matching property in the comment JSON. No drift between markup and attributes.

Once a layout passes review on this subdomain, it gets ported to tiwa.co.id with the same block structure.
