Extracted from atomic-design-poc: RemoteData<E,T> (bare union + fromResource, no combinators) + a trimmed <app-async> switch, no Elm-style store — state is resource() plus one plain signal. Minimal DDD layering per context (domain/infrastructure/application/ui) combined with atomic design inside ui/ (atoms/molecules/organisms/templates/pages), mirroring the POC's conventions at template scale. One worked feature (users/): a list with a click-through to a detail view (its own independent resource() fetch) and a Back action. Tests are BDD-style (describe/it, one assertion per it) and black-box (assert rendered DOM/emitted events only) - 100% branch/line coverage. README.md documents what's deliberately omitted vs. the POC and the concrete growth path back to it. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
