# Design synthesis



Start from the selected base site. Do not edit comparison snapshots or sibling candidates. Write synthesis-plan.json before changing the final site.



Keep the selected global theme. Translate donor composition, media, or behavior into that theme; do not copy a donor stylesheet wholesale. Copy media by stable asset ID with provenance. Reconcile component names and shared CSS. Preserve destination copy and actions unless those facets were selected.



Do not invent identities, testimonials, projects, facts, or working integrations to make a donor section fit. If evidence is missing, adapt the structure to verified material or record the unresolved need.



Rerun representative quality, whole-site visual/content, browser/function, and feedback-fulfillment checks on the synthesized site. Element selection does not approve the donor candidate as a whole or the resulting final site.
