/* ICore — UCIM EI/EX Skeleton (shared front-end contract)
 * USE/UIX adoption: every ICore subdomain imports this shell so 19 surfaces
 * feel like one place. EI = what an entity presents; EX = how it feels over
 * time. "Entity" = human-first, entity-generic. Zero dependencies, vendored.
 * Progressive disclosure: Human (minimal/guided) vs Professional (inspector). */
