Operator correction: designs live at the Solution-Design level — one subfolder
per spec (ui/designs/SD-0001/), not per slice.

Standard third content-repo collection alongside specs/ and plans/: UI-design
artifacts (Claude Design outputs generated from a Solution Design), referenced
from specs. Spec-linkage gate + backfill gesture tracked in
wiggleverse-dev-claude-plugin#93.
