Shared base over Shadcn: layout, nav, pipeline table/log/telemetry, auth chrome, explainers, route shell, product route helpers.

Status (Phase 1): sources live here (moved from components/base/bitcode/). routes/product-routes.ts is the canonical Packs/Reads/Deposits route helper.

Import only from: components/shadcn (and @bitcode/styling / packages).

Next: Phase 2 renames execution/ → pipeline/ and product Execution UI symbols to Pipeline.
