# @omnibioai/ui is a file: dependency consumed as prebuilt dist/ output
# (its package.json main/module/css all point into dist/). .dockerignore
# excludes **/dist from the build context, so unlike a host checkout where
# dist/ was already built once, the copied packages/omnibioai-ui here has
# none — it has to be built explicitly or `npm run web:build` fails to
# resolve "@omnibioai/ui/dist/index.css" from src/ui/main.jsx.
# @omnibioai/design-tokens needs no such step — it ships plain source files
# (tokens.css/.js/.ts) directly, per its package.json.
# npm ci here fails: packages/omnibioai-ui/package-lock.json is out of sync
# with its own package.json (missing the @omnibioai/design-tokens entry) —
# a pre-existing issue in that package (it has its own repo, see its
# package.json "repository" field), not something to hand-patch in a
# vendored lockfile from here. `npm install` reconciles it instead of
# failing strict the way `ci` does.
