## Build and test workflows

- Run `yarn build-modules` to execute the existing ocular and lerna build flow for modules. The default `yarn build` command delegates to this script for backward compatibility.
- Run `yarn test` to list available test modes, or `yarn test full` for the standard module test suite.
- Run `yarn build-apps` to run the tile-converter app build (currently the only app in this repository).
- Run `yarn test-apps` to exercise the tile-converter app test/build script when available.
