Mix any chrome
The frame around every page is a part too: 16 headers and 16 footers from the engine's chrome registry. 14 of them are mixable — selectable on ANY design — while the signature premium chrome stays locked to the design it was drawn for. Compose them in the Mixer, set them in /admin/designs, or ship them in a composition file.

Chrome is governed data, not a fork
Picking a header or footer writes one small setting (chromeJson) — the design, palette and copy stay untouched, and unset always means the design's own default. Agents set it with the audited chrome.set tool; compositions carry it as { chrome: { headerKey, footerKey } }.
