description	Build a feature's ui/ layer — presentation bound to the main-service database. The final, top layer.
input	feature
output	feature

Create ui/: one folder per UI unit — <name>/{<name>.ts (lazy wrapper), <name>-element.ts (container), <name>-presentation.ts (pure render), <name>.css.ts}. The element subscribes to state and delegates to the pure presentation; no business logic here.

Comes last. The how is in the auto-loading features/ui/index.md rule (and element.md, lazy-element.md, presentation.md).
